中文摘要:

为了提高电力线通信的可靠性，对G3-PLC物理层规范进行了改进，给出了一种基于LDPC编码/译码的G3-PLC模型。改进模型将G3-PLC物理层规范中的RS编码/译码功能模块分别替换为LDPC编码/译码功能模块。结合G3-PLC物理层规范，实现了面向该规范的LDPC编码与译码功能。在Simulink环境分别建立了G3-PLC物理层规范模型和改进的物理层规范模型，分析验证了所提改进模型的有效性。改进模型为LDPC应用于基于G3-PLC规范的系统设计提供了一定参考。

英文摘要:

In order to improve the reliability of power line communication , a improved model of G3-PLC physical layer specification based on LDPC encoding / decoding were proposed. In the improved model, the RS encoding / decoding function modules in the G3-PLC physical layer specification were replaced by the LDPC encoding / decoding function modules respectively. According to the G3-PLC physical layer specification, the LDPC encoding and decoding function were realized. The G3-PLC physical layer specification model and the improved physical layer specification model were built respectively in the Simulink software, the validity of the improved model were confirmed. The improved model provides a reference for the application of LDPC to the system design based on G3-PLC specification.
