Abstract

In OFDM transmission, performance is degraded by the existence of time domain impulse noise because its influence spreads over the whole carriers by the DFT operation in the receiver. Especially influence of the impulse noise whose amplitude is large is very severe. In this paper, the scheme of improving influence of impulse noise in OFDM transmission is proposed. In the proposed scheme, the symbols after decision are remodulated to generate a time domain signal to replace the samples that are degraded by the impulse noise in the time domain. The time domain signal where the influence of the impulse noise is reduced is demodulated again. This results in the improvement of bit error rate. Moreover, the performance of the proposed scheme can be more improved by iteratively applying the proposed scheme.
