The paper examines the decoding of low-density parity-check codes in channels with memory. Exact degree distributions optimized for a set of parameters of Gilbert and Gilbert-Elliott channels are given. The decoding performance of low-density parity-check codes constructed using obtained degree distributions are presented under belief propagation decoding over Gilbert-Elliott channel.
