摘　　要：电力线载波通信技术的推广和应用一直受到电力线恶劣信道特性和复杂噪声分布的制约。为了克服这些问题以达到更加稳定、安全、高速率的通信水平,本文设计了一个基于G3-PLC标准的高速窄带电力线载波通信平台。采用FPGA实现了发送机和接收机信号处理的全部过程,应用了正交频分复用,即OFDM调制解调技术、卷积编码译码等技术,并进行了较详细的仿真论证,实现了预期的功能。The promotion and application of PLC technology has been restricted by the power line's bad channel characteristics and noise distribution. In order to overcome these disadvantages and achieve more stable,secure and high speed level of communication. The writer designed narrow-band high speed PLC communication platform based on G3-PLC. A FPGA was used to achieve the procedure of signal processing of transmitter and receiver. During which the OFDM technology,convolutional coding technology and Viterbi decoding were used. At last,the system is verified by a simulation and achieved desired function.
