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.
