摘要
基于软件无线电思想介绍了一种可行的中频数字化接收机系统设计方案。该方案采用HARRIS公司的可编程四通道数字下变频器HSP50216,结合TMS320VC5402 DSP、EPM7064 EPLD构成核心处理单元,实现对不同类型信号的解调。文章给出了整个系统的实现方案,介绍了主要芯片的功能特性和关键部分的硬件连接,最后对系统工作过程进行了频谱分析。
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.
