Abstract

Abstract: The implementation of high-speed data communication through power lines is always a difficulty in the fields of power communications and power system automation．In this paperthe equivalent M-band discrete wavelet transmission mode of OFDM transmission systems was derived based on wavelet transform．A new OFDM-CDMA communications system for high-speed power line communications was then presented on the basis of orthogonal Mband discrete wavelet transform．The computer simulation results indicate that the proposed system is of much better ability to suppress inter-channel interferenceinter-symbol interferencemult-i user interference and noise interference and is applicable to the high-speed power line communications.

Key words: wavelet transform, power line communications, OFDM, CDMA
