摘　　要：由于低压电力线的信道特性是复杂多变的 ,如何利用低压电力线实现可靠且具有较高通信速率的通信 ,一直是电力线通信领域的热点问题。笔者把MSK应用于低压电力线通信 ,分析了MSK的应用原理 ,构建了基于MSK的低压电力线通信系统模型。仿真结果表明 :MSK调制技术较好地满足了电力线通信信道有效带宽窄、对信号振幅的衰减具有时变性和频率选择性的特点 。For that the characteristics of low voltage power line channel are complicated and variable, how to use low voltage power line to realize reliable and high speed communication has always been the hottest question in power line communication field. This article introduces how to apply MSK to the low voltage power line communication. It analyses the application elements of MSK and structures the model of low voltage power line communication based on MSK. simulation result indicates that MSK modulation technology can satisfy the characteristics that the bandwidth of power line communication channel is narrow and the attenuation to the amplitude of signal is time variable and frequency selected. Also, it makes better use of the spectrum.
