Channel coding based on power line communication

摘要

This paper focuses on the forward error correction (FEC), the basic parameters determination of the RS convolution code, Turbo code and the LDPC code, and the corresponding encoding and decoding algorithm in power line communication (PLC) standard. Simulation experiment which is designed for narrow-band power line communication system based on OFDM is done. The coding using RS convolution code, Turbo code, and LDPC code are compared, and further it is determined that which encoding method is more suitable for power line communication in China.
