DEVELI, Ibrahim  and  KABALCI, Yasin. A comparative simulation study on the performance of LDPC coded communication systems over Weibull fading channels. J. appl. res. technol [online]. 2016, vol.14, n.2, pp.101-107. ISSN 2448-6736.  https://doi.org/10.1016/j.jart.2016.04.001.

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

Keywords : Bit error rate performance simulation; Low-Density Parity-Check codes; Weibull fading channels.
