Influence of data frame duration on performance of BITCM system over HV power line

The impulse noise in the HV power line channel is mainly caused by high voltage existing on conductors and station apparatus. Such impulse noise has repetition rate of SO or 150 Hz and is synchronous to power frequency period. In this paper, we have shown that the digital transmission via HV PLC channel have better performance if it is realized through the transmission of interleaved data blocks. The data frame duration must be adjusted to the periodicity of impulse noise or the power frequency period.
