Performance analysis of DF cooperative relaying over bursty impulsive noise channel

The performances of decode-and-forward (DF) cooperative relaying (CR) scheme over channels impaired by bursty impulsive noise are addressed. Unlike the memoryless models of impulsive noise generally considered in the literature, in this paper, the noise is modeled by a two-state Markov-Gaussian process that is able to account for noise time-correlation, as encountered for instance within power substations. For this channel, we evaluate the bit error rate (BER) performance of direct transmission (DT) and a DF CR scheme using BPSK modulation in the presence of Rayleigh fading with a maximum a posteriori (MAP) receiver. From the obtained results it is seen that the DF CR scheme performs significantly better than DT under the same power consumption. Moreover, the proposed MAP receiver is shown to perform very tight to the lower bound derived for DF CR scheme, and performs significantly better than the conventional schemes developed for additive white Gaussian noise (AWGN) channel and memoryless impulsive noise channel.
