Baseband signal processing platform based on software radio

The invention provides a baseband signal processing platform based on software radio. The baseband signal processing platform includes a digital signal processor, a field-programmable gate array connected with the digital signal processor, and an intermediate frequency interface module connected with the field-programmable gate array. The intermediate frequency interface module comprises a digital up-converter and a digital down-converter. The digital signal processor is used for coding and modulating or demodulating and decoding a digital baseband signal. The field-programmable gate array is used for logic programming of the coded and modulated or demodulated and decoded digital baseband signal. The digital up-converter is used for converting the digital baseband signal after logic programming into an intermediate frequency analog signal. The digital down-converter is used for receiving and converting the intermediate frequency analog signal into a digital baseband signal. With the invention, various wireless communication functions can be achieved by loading the software, and in this way, the baseband signal processing platform can have high versatility, a flexible structure, and strong software upgradable and reconfigurable capacities.
