Improving of performance of OFDM reception under Class-A impulsive channel by replica signal estimation of impulse

One of the major factors of performance degradation in OFDM transmission is influence of additive impulsive noise. the proposed scheme using replica signal estimation could improve performance under the impulsive channels. In this paper, the performance of the proposed scheme is evaluated under the realistic channel to enhance usefulness of this scheme. Middleton Class A noise model is used as the realistic channel model. As the result of computer simulation, it was confirmed that the proposed scheme is effective under the Class A noise channel model.
