全数字接收机的DSP实现

全数字接收机是近年来提出的新概念，与传统的模拟接收机不同，全数字接收机解调用的参考载波和采样频率均使用本地时种，不需要利用导频信息来控制；而且它的关键技术都可以采用数字信号处理的方法实现。本文讨论了用ＤＳＰ处理器实现全数字接收机的方法和总控软件的设计。

A DSP Realization of the All-Digital Receiver

The all-digital receiver is a new concept raised these years.It is different from the traditionalanalog receiver.Its referential carrier and sampling frequency are all from the local clock without any controlof the pilot frequency;furthermore,the main module of the all-digital receiver can be realized through DSP(digital signal processing)method. In this paper,we discuss techniques to implement the all-digital receiverbased on the DSP processor,and we also discuss the design of the control software.
