Simulation-Based Validation of Improved BP-Based Decoding Algorithms of LDPC codes (original) (raw)

2008 3rd International Symposium on Communications, Control and Signal Processing, 2008

Abstract

Low-density parity-check (LDPC) codes deliver very good performance when decoded with the BP algorithm. Unfortunately, this algorithm has the disadvantage to be complex for implementation. In this paper, we investigate the BP algorithm and its simplifications (BP-based, normalized BP-based, offset BP-based). Previous works on normalized and offset BP-based proposed theoretical values for the offset and normalization factors, we perform simulations
