Abstract(in English) Power lines are one of the most attractive communication media for access and/or in-home networks. The regulations on power line communication (PLC) may be eased in Japan and we could utilize a frequency band from 2MHz to 30MHz in the future. However, this frequency band often suffers from narrowband interference caused by amplitude modulated (AM) broadcasting and/or amateur ham radio. Therefore, modulation and coding over power line channels are required to have an immunity to narrowband interference. In this paper, we investigate two MCMs, one is OFDM (Orthogonal Frequency Division Multiplexing) with windowing whose window shape is a raised cosine window and the other is Wavelet OFDM, under narrowband interference environments. As these results, we show that Wavelet OFDM has a better performance than OFDM with windowing under narrowband noise environments.
