Abstract :
Multi carrier modulation (MCM) is an attractive approach for high-speed power line communication networks. In a real communication system, the choice of the modulation is one of the most important design steps. In this paper, we analyze and compare the performance obtained in power line networks when using orthogonal frequency division multiplexing (OFDM) or discrete wavelet multi tone (DWMT) modulations. We show that, due to the multi-path, OFDM performance is better than DWMT performance in power line communications.
