摘　　要：软件无线电概念对于通信系统的发展起到了巨大的引导作用,实现软件无线电台的关键之一就是要解决多模式调制解调的软件化问题。本文从信号空间映射的角度,详细介绍了各种数字信号调制解调的通用模式。Software Defined Radio (SDR) is a new architecture of communication system that is brought forward these years in radio area. The modulation and demodulation module of high performance, high spectral efficiency is the key technology of the mobile communication system and its realization using software is an important link of realizing SDR.This paper mainly introduces the universal module of all kinds of digital mokulation and demodulation.
