基于MATLAB平台的通信系统的仿真，RS编码，OFDM调制，加入PLC信道噪声，并进行误码率的检测，运行无误，程序完整。-MATLAB-based communications system simulation platform, RS coding, OFDM modulation, adding PLC channel noise, and make BER testing, run correctly, the program integrity.

本文先简要介绍了OFDM的基本原理，然后进行了OFDM添加循环前缀后可以抗多径干扰的数学推导，在给出OFDM系统模型的基础上，用MATLAB语言对系统进行了仿真。最后给出不同信道下，循环前缀、均衡技术对系统误码率影响的比较曲线，并得出结论。-This paper first introduces the basic principles of OFDM, and then after the OFDM cyclic prefix can be added anti-multipath inter
