- Abstract
- In this paper, we propose a combination of stopping criteria for BP decoding of LDPC codes effective on both high and low SNR and scalable to variable rate and length codes. The proposed algorithms combine three distinct criteria for decoding including conventional syndrome stopping. Each criterion is extremely simple and shall not be a burden to overall system. With these criteria, it is shown that the decoding complexity of H-ARQ system with AMC scheme can be reduced.
