Abstract
The invention discloses a method for obtaining data by a mobile terminal. Radio frequency signals are received and processed through a plurality of multi-antenna receiving circuits, and bit streams output by constellation demodulation units in the circuits are weighted and merged for neutralizing the influence of external factors on the signals, so that the obtained data is more accurate and the signal receiving sensitivity of the terminal is increased.
Description
Technical field
The present invention relates to communication technical field, be specifically related to a kind of method of acquisition for mobile terminal data.
Background technology
Mobile Multimedia Broadcasting is portable terminal sends the multi-medium datas such as digital audio or video with the form of broadcasting business, multimedia mobile terminal is the receiving terminal of multimedia broadcasting, possess reception to radiofrequency signal, conversion, solution and be in harmonious proportion the abilities such as error correction decoding, but because signal can be received the problems such as noise, fading channel in transmission course, the signal of receiving and the signal of transmission there are differences, and accuracy is lower.
Summary of the invention
The object of the invention is to the not high enough problem of signal accuracy that receives according to present multimedia mobile terminal, provide a kind of and can make the accuracy of the signal that multimedia mobile terminal receives and the method that sensitivity all increases.
Above-mentioned purpose of the present invention is achieved by the following technical programs:
A kind of method of acquisition for mobile terminal data, described terminal is multimedia mobile terminal, comprise receiving circuit, weighting merge cells and error correction demodulating unit more than 3 or 3, described receiving circuit comprises antenna, tuned cell, AD conversion unit, OFDM demodulating unit and constellation soft demodulation; Described weighting merge cells comprises weighting parameters acquiring unit, multiplier, adder and soft bit interception unit, and wherein, weighting parameters acquiring unit, multiplier are corresponding with receiving circuit;
Constellation soft demodulation in the described receiving circuit is sent the bit stream of output into the weighting merge cells; The weighting merge cells is weighted the merging processing after receiving bit stream, exports the error correction demodulating unit to; The error correction demodulating unit carries out the error correction demodulation process to the bit stream that receives, and obtains data;
Described weighting parameters acquiring unit obtains the weighting parameters of weighting merge cells in the corresponding receiving circuit; After the weighting parameters that multiplier obtains bit stream and the corresponding weighting parameters acquiring unit of constellation soft demodulation output in the corresponding receiving circuit carries out multiplying, export to adder; Adder is used for the bit stream of multiplier output is carried out exporting after the add operation; The bitstream length requirement according to the rules of soft bit interception unit with the length of bit stream intercepting for requiring of adder output, is exported to the error correction demodulating unit;
The method of acquisition for mobile terminal data of the present invention is bit streams of the constellation soft demodulation output in the receiving circuit, is weighted to merge to export to the error correction demodulating unit after processing and carry out the error correction demodulation process, obtains multi-medium data; Described weighting merges that to process be that bit stream with weighting parameters value and constellation soft demodulation are exported carries out multiplying, and the bit stream of gained carries out add operation again.
As a kind of preferred version, the receive frequency of the tuned cell in the described receiving circuit is identical; The weighting parameters that described weighting parameters acquiring unit obtains is signal to noise ratio or yield value.
Compared with prior art, the present invention has following beneficial effect:
By the present invention many receiving circuits of many antennas are received and process radiofrequency signal, by the bit stream to constellation soft demodulation output in many circuit be weighted merge to come in and uncertain factor to the impression of signal, improve the accuracy of signal, and then multimedia mobile terminal is improved the receiving sensitivity of signal.
