软件无线电中8PSK信号的下变频实现

The Downconverting Realization of the Applied 8PSK in Software Radio

介绍了可编程数字下变频器件HSP50214B的内部结构、功能模块及其在全数字接收机中的应用,其后结合一种实际的信号,重点论述了下变频实现各模块的设计过程,最后参照下变频编程写入的时序逻辑,简要给出如何使用硬件描述语言对其控制字进行编程,从而实现了其在硬件系统中的应用。

This paper introduces the structure and functional blocks of the HSP50214B programmable downconverter and its application in digital receiver. it emphatically discusses the device of the realization of its downconverting through a kind of realistic signal. At last in according to its writing logic, it introduces how to achieve the application in hardware system through making use of the hardware description language.
