中文说明：分析了电力线信道的特性，对电力线信道进行了建模，最终仿真出了多径电力线信道，并且分别在低压、中压环境下进行仿真，仿真结果有频域的幅度相应好有时域的冲击响应。
English Description：
Analysis the characteristics of power line channel, is used in the simulation of power line channel. Finally the simulation the multipath powerline channel, and in low, medium environment simulation, the simulation results of frequency domain amplitude corresponding time domain impulse response.
