摘要
针对电力线通信信道的特点,提出了将ICA算法应用于电力线通信系统的方案,并根据电力线的传输特性,构建了系统模型。实验和仿真表明该系统模型能有效地从传输信号中提取弱信号,并进行正确的解码,从而增加了传输距离,而且此系统约束条件少,具有很强的通用性。
According to channel characteristics of power line communication （PLC）, a scheme of applying independent component analysis to PLC system was proposed. The system model was constructed by the transmission characteristic of power line. The experiment and simulation show that the weak signals can be extracted and decoded from the transmission signals accurately, so that the distance of transmission can be improved. The model requires less restriction conditions which makes the model versatile in engineering.
