摘要:Abstract: Low density parity check code (LDPC) is a subclass of linear block code with sparse check matrix. Sum-product algorithm is efficient for decoding LDPC theoretically, but not practically due to its complexity. Improved algorithms including minimum sum algorithm reduce computational com-plexity by approximation but performance is degraded. In this paper, we introduce corrected sum-product algorithm based on synchronized information, which improves the practicability by reducing the iterations without performance degradation.
