A comparative simulation study on the performance of LDPC codedcommunication systems over Weibull fading channels

Ibrahim Develi, Yasin Kabalci


The Weibull distribution is a useful statistical model that can be used to describe the multipath fading in nowadays wireless communicationenvironments. In this paper, the bit error rate (BER) performance of Low-Density Parity-Check (LDPC) coded communication systems usingdifferent decoding rules is presented over Weibull fading channels by means of comparative computer simulations. It is shown that, especiallyfor the case of the Belief Propagation (BP) decoding rule, significant performance improvement can be achieved in comparison with uncodedtransmission when the channel is assumed to have Weibull fading.
