Description

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. In this paper, the scheme that reduces the influence of impulse noise under multi-path channels is proposed. In the proposed scheme, replica signal of the impulse noise is used. In the receiver, amplitude, phase, and time position of the impulse noise are estimated and the replica signal of the impulse noise is generated using the estimated parameters. By subtracting the replica signal from the received signal, the additive impulse noise can be reduced.
