Abstract :
Several popular, suboptimal algorithms for bit decoding of binary block codes such as turbo decoding, threshold decoding, and message passing for LDPC, were developed almost as a common sense approach to decoding of some specially designed codes. We explain exactly how they approximate the optimal decoding algorithm, and show how good this approximation is in some special cases
