摘　　要：研究了利用PN序列得出电力线信道冲激响应的方法,该方法能快速地得到信道的冲激响应,并经过快速傅里叶变换得到信道的传输函数.用该方法研究了150m、250m、350m长度电力线信道的传输函数,并与矢量网络分析仪测量的实际信道传输函数进行了对比验证.A method to achieve the impulse response of power line communications（PLC） channel based on the PN sequence is studied in the paper. The method can gain the channel＇ s impulse response accurately,and gain the transfer function by FFT operations. Transfer function is studied in 150 m/ 250 m/350 m PLC channel,and is contrasted with the vector network analyzer（VNA）＇s measurement results. The comparison results show that we can get the accurate channel function through the PN sequence methods.
