摘要

介绍了比特交织turbo编码调制(BITCM)技术在电力线信道中的性能,并与AWGN信道进行了比较。给出了电力网正常运行和恶劣天气条件下的噪声特性。考虑脉冲噪声的电力线信道模型适用于信道编码方法的研究。给出了在PLC信道上任意正交调幅的误码率(BER),并以此作为估计编码增益的起点。BITCM系统模型是基于QAM映射的。计算机仿真得到的误码率性能给出了电力线上BITCM通信的基本特性。

Comparison of BITCM performance in dPLC channel with AWGN channel
The performance of bit interleaved turbo coded modulation (BITCM) technique in the power line channel and comparison with AWGN channel is presented. The noise characteristics are given for normal operations of power line network and foul weather condition. The model of power line channel including impulse noise is appropriated for investigation of channel coding methods. The bit error rate (BER) of M-ary quadrature amplitude modulation over PLC channel is given and represents the starting point for coding gain estimation. The BITCM system model is based on QAM mapping. The error rate performance obtained by computer simulation gives the basic characteristics of BITCM in communications over power line.
