Turbo decoding in presence of impulsive noise over Nakagami m fading channel

As the communications systems are seldom significantly interfered with by classical white Gaussian noise, it is necessary to consider other, appropriate (and tractable) interference models, if realistic estimates of system performance are to be obtained for the general spectral-use environment. The statistical characteristics of impulsive noise differ greatly from those of Gaussian noise. Hence, the performance of conventional decoders, optimized for AWGN channels is not promising in non-Gaussian environments. In order to achieve improved performance in impulsive environments the decoder structure needs to be adapted in accordance with the impulsive noise model. For this purpose, Middletonpsilas recently developed canonical statistical-physical model of ldquoimpulsiverdquo interference is applied to real-world communication channels. This paper provides performance analysis of turbo codes over fully interleaved Nakagami-m fading channels with Middletonpsilas additive white Class-A impulsive noise (MAWAIN). Simulation results for memory less Nakagami-m fading channels under coherent BPSK signaling are provided for the cases of ideal channel state information (ICSI) and no channel state information (NCSI) at decoder.
