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,调制解调技术在软件无线电系统中占据着重要的地位.实现软件无线电台的关键之一就是要解决调制解调的软件化问题.文中主要对软件无线电结构下的AM、FM调制解调算法进行研究,并在此基础上用Matlab仿真工具对AM、FM信号的调制解调算法进行仿真实验,从而证明了算法的正确性和可行性.Software Defined Radio （SDR） is a new architecture of communication system that is brought forward these years in radio area,and the modulation and demodulation technology occupies an important position in the software radio system. The modulation and demodulation module is the key technology of the mobile communication system and its realization using software is an important link of realizing SDR. The modulation/demodulation algorithm is mainly studied based on software radio, and the algorithm of AM, FM is simulated on this basis with MATLAB. The simulation shows that the correctness and feasibility of the algorithm.
