Abstract :
In OFDM transmission, performance is degraded by the existence of time domain impulse noise because this noise has very wide bandwidth and it affects all the carriers in the OFDM symbol. Moreover, transmission characteristic is extremely degraded under multi-path channel. Such a situation frequently occurs in power-line communication (PLC) and an appropriate measure is necessary. In this paper, the scheme that reduces the influence of impulse noise under multi-path channels is proposed.
