This paper derives an equivalent M-band discrete wavelet transmission mode of OFDM transmission systems, and presents a new quadrature M-band discrete wavelet-based OFDM-CDMA communication systems for high speed power line communication (PLC) channels. This system gives much better suppression inter-channel interference (ICI), inter-symbol interference (ISI), narrowband interference (NBI), multi-user interference (MUI) and noise interference performance, which is verified by simulation
