Along with the develop rapidly of cordless communication network, the requirement of people to communication quality is also more and more higher, MIMO (Multiple Input Multiple Output, Multiple Input Multiple Output) can make full use of as a kind of the technology that system resource improves communication quality, become the core technology of 4G (the 4th Generation mobilecommunication technology, forth generation mobile communication technology).MIMO refers to that the transmission signal of multiple transmitting apparatus is through the same space transmission, is undertaken receiving and recover the technology of multiple transmission signal by multiple receiving equipment.

When mimo system normally works, need transmitting terminal and receiving terminal all normal.When having transmitting terminal or receiving terminal fault, need to carry out MIMO degeneration, namely will give up the receiving terminal broken down or transmitting terminal, the impact that mimo system is subject to is minimum.For MIMO4 × 4 system, there are 4 transmitting terminals and 4 receiving terminals within the system, concrete configuration as shown in Figure 1, transmission source is made up of two like-polarized transmitting terminal T1, T3 and two heteropolar transmitting terminal T2, T4, and reception source is made up of two like-polarized receiving terminal R1, R3 and two heteropolar receiving terminal R2, R4.When T1 breaks down, R1 can only receive T2, T3, the signal that T4 sends, before T1 breaks down, the symbol clock receiving intermediate frequency 1 always with the symbol synchronizer of T1, after T1 breaks down, R1 need recover the signal of T3, so receive the symbol clock that symbol clock need be resynchronized to T3 by intermediate frequency 1, the process of re-synchronization symbol clock can cause the symbol clock receiving intermediate frequency 1 to shake, and also need to use the symbol clock receiving intermediate frequency 1 to be removed to read the symbol data receiving intermediate frequency 3 by interface simultaneously, the shake of symbol clock can cause the frame length of a certain frame in the symbol data of the reception intermediate frequency 3 read elongated or shorten, thus cause the frame head of the symbol data of the reception intermediate frequency 3 using the symbol clock receiving intermediate frequency 1 to be read by interface to move.

When mimo system is just started working, 4 symbol datas receiving intermediate frequency can carry out a frame alignment, the symbol data input equalizer of 4 road close alignment just can be recovered the signal that 4 receiving terminals send, but MIMO degeneration causes the frame head of a wherein road symbol data to move, the frame head of the symbol data on a wherein road can be made not align with the frame head of the symbol data on other three tunnels, thus cause the signal that correctly cannot recover transmitting terminal transmission, cause MIMO communication quality poor.

Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.

The embodiment of the present invention provides a kind of processing method of Frame, the method is applied in mimo system, described mimo system comprises at least two transmitting terminals and at least two receiving terminals, each receiving terminal all can receive the signal that all transmitting terminals send, wherein, the road signal to be restored that each receiving terminal receives is main path signal, the signal except main path signal that each receiving terminal receives is tributary signal, main path signal and tributary signal all transmit with the form of data flow, data flow is made up of multiple Frame, as shown in Figure 2, the method comprises:

201, the Frame of frame head adjustment equipment parallel receive main path signal and the Frame of single tributary signal.

Be understandable that, the Frame of main path signal and the Frame of single tributary signal are parallel transmissions, when mimo system normally works, first Frame of single tributary signal is received while frame head adjustment equipment receives first Frame of main path signal, the Frame of main path signal and the Frame of single tributary signal are relations one to one, when MIMO degenerates, the frame head of Frame of the main path signal that frame head adjustment equipment is currently received and the unjustified situation of frame head of the Frame of the tributary signal be currently received can be there is.

202, the position relationship between frame head adjustment equipment real-time detection branch N data frame head and main road N data frame head, branch road N data frame head is the frame head of N number of Frame of the single tributary signal be currently received, and main road N data frame head is the frame head of N number of Frame of the main path signal be currently received.

Wherein, position relationship comprises alignment relation and unjustified relation, N be more than or equal to 1 integer.

203, when frame head adjustment equipment determination position relationship is unjustified relation, unjustified instruction is sent to treatment facility.

204, the adjustment that frame head adjustment equipment receiving and processing equipment sends indicates, by the Frame of the single tributary signal of adjustment instruction adjustment, align with the frame head of the Frame of the frame head with main path signal that make the Frame of single tributary signal, adjustment is designated as the instruction of the data frame length for adjusting single tributary signal.

What deserves to be explained is, the reason that main road N data frame head and branch road N data frame head do not line up is that the length of a certain Frame in tributary signal there occurs change, so the length of adjustment tributary signal Frame can make the frame head of the Frame of tributary signal subsequent transmission align with the frame head of the Frame of main path signal subsequent transmission.

The processing method of the Frame that the embodiment of the present invention provides, by the Frame of parallel receive main path signal and the Frame of single tributary signal, position relationship between real-time detection branch N data frame head and main road N data frame head, when determining that this position relationship is unjustified relation, unjustified instruction is sent to treatment facility, then the adjustment that receiving and processing equipment sends indicates, by the Frame of adjustment instruction adjustment tributary signal, align with the frame head of the Frame of the frame head with main path signal that make the Frame of single tributary signal.With in prior art because the frame head entering the Frame of the tributary signal of equalizer does not align with the frame head of the Frame of main path signal, and cause the signal that cannot recover transmitting terminal to be compared, the present invention tributary signal and main path signal are carried out balanced before, branch road N data frame head and main road N data frame head are detected, and the Frame of the single tributary signal of adjustment in real time, the Frame of single tributary signal after adjustment is made to carry out balanced with the Frame of main path signal with the state of aliging, thus correctly recover the signal of transmitting terminal, improve MIMO communication quality.

Be understandable that, described above is the method that the frame head of the Frame of single tributary signal is alignd with the frame head of the Frame of main path signal.In mimo systems, multiple tributary signal situation may be there is, such as in the system of MIMO4 × 4, the corresponding main path signal of each receiving terminal and three tributary signals, the position relationship of the frame head of each tributary signal Frame of frame head adjustment equipment independent detection and the frame head of main path signal Frame, and adjust according to the Frame of position relationship to tributary signal, detect the data frame head of each tributary signal identical with the method for the data frame head of main path signal.

Specifically as shown in Figure 3, in the system of MIMO4 × 4, for in chip 1 from the receive path 2 received between intermediate frequency 2 to balanced 2, at four road signal S1, S2, S3, S4 after frame alignment, enter frame head adjustment equipment, frame head adjustment equipment has preamble detecting as shown in Figure 3 and frame head adjustment function.Because the signal to be restored of balanced 2 is S2, so S2 is main path signal, S1, S3, S4 is tributary signal, preamble detecting in Fig. 3 need detect S1 simultaneously, S3, the frame head of the Frame of S4 respectively with the position relationship of the frame head of the Frame of S2, when the position relationship of the frame head of the frame head of Frame and the Frame of S2 that a certain branch road detected is unjustified relation, such as detect that the position relationship of the frame head of the frame head of the Frame of S3 and the Frame of S2 is unjustified relation, the unjustified instruction of S3 is then sent to CPU, and then after frame head adjustment receives the adjustment instruction of the S3 that CPU sends, adjust the length of the Frame of the S3 be currently received.Position relationship between the frame head detecting the frame head of the Frame of each tributary signal and the Frame of main path signal is independent of each other.

What deserves to be explained is, each preamble detecting shown in Fig. 3 adjusts with frame head and all can communicate with CPU, and CPU is the treatment facility in Fig. 2 embodiment.

The present invention puies forward the processing method also supplying a kind of Frame, and as shown in Figure 4, the method comprises:

401, the Frame of frame head adjustment equipment parallel receive main path signal and the Frame of single tributary signal.

402, frame head adjustment equipment Inspection branch road N data frame head is relative to the skew polarity of main road N data frame head, and when receiving branch road N data frame head in the ban, skew polarity is just, when receiving main road N data frame head in the ban, skew polarity is negative.

What deserves to be explained is, when frame head adjustment equipment first receives branch road N data frame head, illustrate that branch road N data frame head is ahead of main road N data frame head, so branch road N data frame head is just relative to the skew polarity of bypass data frame head; When frame head adjustment equipment first receives main road N data frame head, illustrate that branch road N data frame head falls behind and main road N data frame head, so branch road N data frame head is negative relative to the skew polarity of bypass data frame head; When to receive main road N data frame head and branch road N data frame head simultaneously, illustrate that branch road N data frame head is synchronous with main road N data frame head, without skew polarity.

403, frame head adjustment equipment Inspection branch road N data frame head is relative to the side-play amount of main road N data frame head.

Wherein, side-play amount is the symbol numbers at interval between main road N data frame head and branch road N data frame head, and symbol is the unit of measurement of Frame, and a Frame is made up of multiple symbol.

The concrete grammar detecting side-play amount is: when frame head adjustment equipment receives first via data frame head, symbol counter starts counting, and first via data frame head is main road N data frame head or branch road N data frame head;

When frame head adjustment equipment receives the second circuit-switched data frame head, symbol counter terminates once to count, and the value of symbol counter is side-play amount, and the second circuit-switched data frame head is main road N data frame head or branch road N data frame head.

When first via data frame head is main road N data frame head, the second circuit-switched data frame head is branch road N data frame heads, and when first via data frame head is branch road N data frame head, the second circuit-switched data frame head is main road N data frame heads.

Be understandable that, when to receive first via data frame head and the second circuit-switched data frame head simultaneously, side-play amount is 0.

First receive main road N data frame head for frame head adjustment equipment, when receiving main road N data frame head, symbol counter starts counting, and when receiving branch road N data frame head, symbol counter terminates this time counting; When then receiving the frame head of N+1 Frame of main path signal, symbol counter restarts counting, when receiving the frame head of N+1 Frame of single tributary signal, symbol counter terminates counting, continues the side-play amount of frame head relative to the frame head of main path signal Frame of the subsequently received single tributary signal Frame of detection according to the method.

404, when frame head adjustment equipment determination position relationship is unjustified relation, unjustified instruction is sent to treatment facility.

Wherein, unjustified instruction comprises position relationship, and position relationship comprises skew polarity and side-play amount.Send unjustified instruction to be used for informing that treatment facility branch road N data frame head and main road N data frame head are unjustified relation.

Be understandable that, unjustified relation refers to that frame head adjustment equipment does not receive main road N data frame head and single branch road N data frame head simultaneously.

405, when side-play amount is different relative to the side-play amount of the frame head of N-1 Frame of main path signal from the frame head of N-1 Frame of single tributary signal, the adjustment instruction that frame head adjustment equipment receiving and processing equipment sends.

Wherein, adjustment is designated as the instruction that treatment facility is determined according to position relationship.When skew polarity is timing, adjustment is designated as increases symbol instruction, and when offseting polarity for time negative, adjustment is designated as and reduces symbol instruction.

406, when frame head adjustment equipment is determined to receive the instruction of increase symbol, in the data division of the Frame of the tributary signal be currently received, at least one symbol is increased.

What deserves to be explained is, Frame is made up of frame head, data division and postamble, in order to not destroy the structure of Frame, only adjusts the data division of Frame.

When frame head adjustment equipment receives the instruction of increase symbol, illustrate that some Frames of tributary signal decrease symbol and cause this Frame to shorten, and then when causing the subsequent data frame of tributary signal to be transmitted, the frame head of the Frame of tributary signal is ahead of the frame head of the Frame of main path signal, so now increase at least one symbol in the data division of the Frame of the tributary signal be currently received, to make Frame elongated, the frame head of the Frame of subsequently received tributary signal is delayed, the frame head of the Frame of tributary signal is finally made to align with the frame head of the Frame of main path signal.

As shown in Figure 5, main path signal and tributary signal parallel transmission in the direction of the arrow, oblique line portion is the frame head of Frame, and dash area is the postamble of Frame, is the data division of Frame between frame head and postamble, and in figure, little lattice represent a symbol.Branch road first data frame head is that the state of aliging is transmitted with main road first data frame head, branch road second data frame head is also that the state of aliging is transmitted with main road second data frame head, but the data division of second of tributary signal Frame lost a symbol, cause second Frame to shorten, make branch road the 3rd data frame head be ahead of main road the 3rd data frame head 1 symbol.

Frame head adjustment equipment can detect that the position relationship of branch road the 3rd data frame head and main road the 3rd data frame head is unjustified relation, side-play amount is 1, skew polarity is just, send unjustified instruction to treatment facility afterwards, continue the position relationship between detection branch the 4th data frame head and main road the 4th number frame head simultaneously, the adjustment instruction that treatment facility sends is have received while detecting, then increase a symbol at the data division of the 4th Frame of tributary signal, make the 4th of tributary signal the Frame elongated, thus branch road the 5th data frame head is alignd with main road the 5th data frame head.

In addition, position relationship between branch road the 4th data frame head that frame head adjustment equipment Inspection is arrived and main road the 4th number frame head is still unjustified relation, side-play amount is 1, skew polarity is just, frame head adjustment equipment can send unjustified instruction to treatment facility, but because branch road the 3rd data frame head is also 1 relative to the side-play amount of main road the 3rd data frame head, so the adjustment instruction that treatment facility sends can not be received.

407, when frame head adjustment equipment is determined to receive the instruction of minimizing symbol, a symbol is reduced by least at the data division of the Frame of the tributary signal be currently received.

What deserves to be explained is, in order to not destroy the structure of Frame, frame head adjustment equipment often receives and once adjusts instruction, general only at data division increase or a minimizing symbol of the Frame of the tributary signal be currently received.
