摘要
针对低压电力线信道的多径衰减效应,在分析低压电力线信道噪声、衰减和多径特性的基础上,提出采用分集技术降低通信系统误码率的解决方案,并使用矩阵实验对其模型进行仿真验证。仿真结果表明:最小频移键控的电力通信系统采用分集技术可抵抗多径效应。
Aiming at multipath fading effect of low-voltage power line communication channel, based on analysis the noise,fading and multipath characteristic of low-voltage power line commu-nication channel,puts forward the solution of using diversity technology reduce the error rate of the communication system,and using a matrix laboratory verifies its model by simulation method. The simulation result shows that using diversity technology the power communication system with mini-mum shift-frequency keying modulation can resist multipath effect.
