ABSTRACT
Radio receiver, as an extensively feasible modern technology, has been widely applied in all fields of military and civil. It is mainly to demodulate all kinds of required signals with strong interference and noise. Based on intermediate frequency (IF) software radio receiver test platform, the data transmission approach combining direct memory access (DMA) and multichannel buffered serial port (McBSP) was studied and the parallel operation of data transmission and data processing was realized. The method proposed for signal transmission and processing shows strong universality and can be used in other relevant fields.
