软件无线电接收机设计实现

he design and implementation of a SDR receiver which is broadband and highly dynamic is concentrated primarily on in the paper. Concepts of broadband and optimization method of IF noise bandwidth are applied to the design of the SDR receiver. At last, the performance of the AFE of the receiver is verified with the spectrum analyzer. The realization of the receiver has reference value for the design of base station receivers, spectrum analyzers and other applications. More than that, it provides a universal platform for algorithm research on SDR and cognitive radio (CR).
