摘要
近年来,软件无线电作为第三代移动通信系统中解决通信体制兼容性问题的重要方法受到各方面的关注。其中高性能、高频谱效率的调制解调模块是移动通信系统的关键技术,他的软件化也是实现软件无线电的重要环节。本文讨论了在未来移动通信系统中比较关键的16QAM调制解调技术的原理,并给出了用美国ELANIX公司的动态系统设计、仿真和分析软件SystemView进行系统仿真的具体设置,分析了仿真结果。同时,在分析了用FPGA实现软件无线电的优势后,提出了用FPGA技术实现这种系统的详细方法。
In recent years, Software Defined Radio（SDR） is proposed as the important method for compatibility of the different communication system in the third generation mobile communication system and is payed close attention to by many country and institution. 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 discusses the principle of one of the key modulation （demodulation） technologies of 16QAM in the future. It Carries on simulation with the dynamic system design, Simulation and analyses software-U.S.A. ELANIX Company＇s SystemView and analyses the simulation result. At the same time, after this paper is analyse the advantage of realizing SDR with FPGA, puts forward the method to use FPGA technology for achieving the 16QAM modulation and demodulation system.
