Efficient LDPC Decoding Algorithm Based on Min-sum
摘要
Abstract
To improve the decoding performance of Low Density Parity Check(LDPC) code, an efficient decoding algorithm based on rain-sum algorithm is proposed. The proposed algorithm analyzes the check node update equation and at the view of probability to form an approximation rain-sum equation. It adopts a dynamic normalization factor to improve the decoding performance. Detailed simulation results and comparisons with Belief Propagation(BP) algorithm show that, with little decoding performance loss, the proposed algorithnl not only decreases computational load, but also improves decoding efficiency.关键词
