Abstract

A feasible digital intermediate frequency receiver based on software radio technology is presented in this paper.Its key unit consists of the four-channel programmable digital down-converter HSP50216,TMS320VC5402 DSP and EPM7064 EPLD.It can carry out many forms of signal receiving effectively by using the same hardware.It provides a scheme to realize the whole system.And then,the characteristic and performance of main chips and their connections are introduced in details.Finally,frequency spectral analysis is discussed as well.
