摘　　要：随着通信技术的发展,通信系统的研究成为一项越来越复杂的工程,所以,对通信系统的仿真就日益成为一种重要的研究手段。本文介绍一种对CDMA码分多址通信系统进行计算机仿真的方法。该方法基于通信过程的基本特征,充分利用软件系统的技术特点,具有非常好的可扩展性和执行速度。通过把仿真结果同理论结论进行对比,证明该仿真方法非常有效。The study of communication system is becoming complex more and more when the communication technology is rapidly developing. So the computer simulation for communication system is considered as a very important study method. A simulation method for CDMA communication system is presented. Based on the typical feature of the communication process, using the technology character of software, it has strong expansibility and good speed. It is proved highly effective through comparing the simulating result and the analysis result in theory.
