A simple stopping criterion for iterative decoding of parallel concatenated LDPC codes

摘要

This paper proposes a simple stopping criterion that based on the statistic of extrinsic information for iterative decoding of parallel concatenated LDPC (Low Density Parity Check) codes. The proposed MEM (Mean of Extrinsic information Magnitude) criterion has low computation complexity and few memory space requirements. Simulations results proved that the MEM rules outperforms the other existing criterions in terms of BER and average number of super iterations1.
