Accompanying drawing explanation
Fig. 1 is the module map of a kind of radio transceiver system in the embodiment of the present invention.
Embodiment
The present invention is by providing a kind of radio transceiver system, the multiple radio transceivers solved in prior art on an equipment are positioned to come in close proximity to each other usually, the phase reception in the same time that can interfere with from radio transceiver transmission on same equipment will be caused, owing to having leakage between adjacent band, even if two radio work over different frequency bands, also can interactional technical problem, and then achieve the mutual interference can effectively avoiding same equipment receiving between radio.
In order to solve above-mentioned technical problem, below in conjunction with Figure of description and concrete execution mode, technique scheme is described in detail.
A kind of radio transceiver system provided by the invention, receives long-range Public Address system for wireless microphone equipment by radio company below and is described in detail.
As shown in Figure 1, this wireless microphone equipment comprises the first radio audio emitter 101 and the second radio audio emitter 102, and this long-range Public Address system comprises the first radio audio receiver 103 and the second radio audio receiver 104.Common crystal oscillator 105 provides clock signal for the first radio audio receiver 103 and the second radio audio receiver 104 simultaneously, and this clock signal is used in particular for regulating flywheel, and this flywheel runs with the fixed frequency of this crystal oscillator.
Be coupling at least one adjustable component 106 of each signal transceiver, wherein, at least one adjustable component 106 comprises switched capacitor bank.The change of the signal received along with radio audio receiver, electric capacity also must change to avoid larger mismatch, provides the combination of the capacitor in the capacitor of highest received signal or Capacitor banks should be selected for the signal receiving this radio frequency.
Above-mentionedly from Capacitor banks, select suitable electric capacity for the radio signal of receiving feature frequency, thus avoid at the needs manufacturing radiophonics frequency receiver derivation antenna offset.
Locate in the time of above-mentioned flywheel timer sets, first radio audio receiver 103 enters receiving mode when the first switching cycle starts, after the first switching cycle time, be switched to sending mode, when the second switching cycle starts, this first radio audio receiver 103 returns to receiving mode; Meanwhile, the running of the second wireless audio receiver 104 is also synchronous, in the time that internal regulation wheel is arranged, when the first switching cycle starts, enters receiving mode, at the end of the first switching cycle, enters sending mode, until the switching of next pattern.
Because two audio receivers operate on public crystal oscillator, its respective regulating wheel is by synchronously, that is, they can not relative to each other drift about.
Wherein, the second wireless audio receiver 104 controls the phase place of internal regulation wheel relative to the regulating wheel the first wireless audio receiver with it from the synchronizing signal that the first wireless audio receiver 103 receives.
When the square wave of the first wireless audio receiver 103 Drazin inverse wheel, second wireless audio receiver produces identical inside square wave, by the justified margin by two square waves, set up a common phase referential, thus make the regulating wheel of adjustment first wireless audio receiver and regulate the regulating wheel of the second wireless audio receiver to keep synchronous.
By above-mentioned technical scheme, the transmission of multiple radio audio receiver can be coordinated, decrease the interference of Received signal strength each other, thus better performance is provided.
