This system transform miltifrequency and multiaccess signals from Intermediate Frequency to Baseband by application of key technologies in Software-Defined-Radio such as Bandpass Sampling,DDC,Decimation and Accesses Separation. The research in the baseband include Signal Type Identification and Digital Demodulation.
本论文利用软件无线电思想中的带通采样技术、下变频技术以及抽取技术对多频多路中频信号进行采样、下变频、抽取、单路信号提取等中频处理,将其变到基带,并对提取出的单路信号进行基带处理,基带处理包括信号调制样式识别和数字解调。
