摘要
运用MATLAB语言编制程序针对电力线进行仿真，仿真通过使用不同的编码解码组合测试系统的误码率性能，在几种调制编码方法中从传输性能上选择适合于低压电力线通信的调制和解调方法，得出QPSK调制方式和R3／4卷积编码方式是比较适合电力线信道的。
This paper, using the MATLAB language, simulates the power line communication , testing the bit error rate of the system by means of different coding and decoding combination. Among several coding and decoding modes, the one that fits the lower voltage power line communication could be chosen based upon the information transmission feathers, and it is concluded that QPSK coding mode and R3/4 convolution coding mode fits the power line channel better.
