摘要

多载波调制(MCM)是高速电力线通信网络的一种有吸引力的方法。在实际通信系统中，调制方式的选择是最重要的设计步骤之一。本文分析并比较了正交频分复用(OFDM)和离散小波多音调制(DWMT)在电力线网络中的性能。我们证明，由于多路径，在电力线通信中，OFDM的性能优于DWMT。

OFDM and wavelets performance comparison in power line channels

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.
