Abstract

As a method to realize a high-speed communication in home network, the power-line communication (PLC) technique is known. In PLC channels, transmission signal quality is degraded by colored non-Gaussian noise with uncommon characteristics as well as frequency-selectivity of channels. In this paper, we investigate the performance of the OQAM-MCT system with a small number of subcarriers where noise canceller is jointly used with time-domain per-subcarrier adaptive equalizer. In addition, we propose a modified noise cancellation method designed for OQAM-MCT system. The performance of the OQAM-MCT system is evaluated in PLC channels with measured impulse responses in presence of measured noise. Computer simulation results show that transmission rate of the OQAM-MCT system is improved by using both adaptive equalizer and noise canceller and also the OQAMMCT system achieves better performance than OFDM system with insufficient length of guard interval.
