用Ansoft Serenade进行通信系统仿真

摘要

With the technique of simulation, experiments can be done difficultly in real system. The technique of simulation can save the cost and speed the development with competition more and more. In this article, the development and application of simulation of communication system as well as the special simulation tool-Anosft Serenade is introduced, the Ansoft Serenade composed of Harmonica and Symphony which are used to the simulation of circuit and communication system respectively. The principle of modulation and demodulation of BPSK is analyzed and simulated using Ansoft Serenade, the result of simulation is given.%借助于仿真技术可进行真实系统难以进行的各种实验。在竞争越来越激烈的今天，利用仿真技术可节约开发费加快并加快开发进程。介绍了通信系统仿真的发展历程及应用，并介绍了专用仿真工具Ansoft Serenade，它由Harmonica和Symphony两部分组成，分别用于电路和通信系统仿真。对BPSK的调制解调原理进行了理论分析，并用Ansoft Serenade对整个过程进行了仿真，给出了仿真结果。
