摘要
在对电力线载波进行介绍的基础上,重点分析了低压电力线载波存在的问题及ASK,PSK,FSK,MSK等几种调制技术的基本原理,分析讨论了它们的优缺点,最后给出了一种应用于低压电力线载波通信的有效技术——OFDM调制技术,分析了其在电力线载波通信中的优越性和需要注意的问题.
Based on the introduction of power line carrier, this paper analyzes selectively the existence of low pressure power line carrier as well as the basic principle of several kind of modulating technology such as ASK, PSK, FSK, MSK and so on, and discusses their good and bad points. Finally this paper gives one effective technology that can be applied in low pressure power line carrier communication： OFDM roodulating technology, and analyzes its superiorities in power line carrier communication and the questions which needed paying attention to.
