Shuffled belief propagation decoding
WebFeb 1, 2015 · This paper proposes a new group shuffled belief propagation (BP) decoding of low-density parity-check (LDPC) codes, which divides check nodes or variable nodes into … WebBased on the LLR-BP decoding algorithm, an improved belief propagation (IBP) decoding algorithm which uses soft information by last decoding is proposed. When the CRC is failed, the soft information from the last decoding, which is higher than the threshold, is reserved as the initial information of the following decoding, which greatly improves the decoding …

WebIn this paper, we present a new low-complexity iterative joint phase estimation and decoding algorithm which can be applied to low-density-parity-check (or turbo) codes for channels affected by strong phase noise. The algorithm exhibits a very good performance and a very low complexity even in strong phase noise, high code rate, and high-order constellations.
