Abstract
LDPC code is a preferred channel code used in modern communication because of its robustness to mitigate the huge noise. In this paper, LDPC with four decoder types is combined with Differential Chaos Shift Keying (DCSK) communication system under AWGN channel. The system is simulated using MATLAB program version 2019a with various amounts of half spreading factor, β ∈ {8, 16, and 32}. The results show that a coding gain is achieved in a range of (1.3 – 4.6) dB between the coded and uncoded DCSK system. Also, log domain decoder is the best decoder among all types, while hard decision bit flipping decoder appears the worst case in contrast with its simplicity.
