Abstract

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.

Description

technical field [0001] The present invention relates to a communication transmission technology of a digital transmission station, and more specifically, to a software radio-based single carrier or OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) transmission technology. Background technique [0002] With the rapid development of science and technology, radio technology has received widespread attention as a new communication system. In radio technology, digital wireless data transmission stations (referred to as digital transmission stations) are widely used. Digital transmission stations refer to high-performance professional data transmission stations realized by DSP (Digital Signal Processing, digital signal processing) technology and radio technology. , but the existing digital radio stations have the following problems: [0003] 1. The digital radio stations are all composed of hardware, which has the disadvantages of singl...
