Early stopping for LDPC decoding: convergence of mean magnitude (CMM)

  title={Early stopping for LDPC decoding: convergence of mean magnitude (CMM)},
  author={Jin Li and Xiao-Hu You and Tiffany Jing Li},
  journal={IEEE Communications Letters},
A new early stopping criterion is proposed for low density parity check (LDPC) codes to reduce the number of decoding iterations while preserving a good decoding performance. The new criterion is based on the convergence of the mean magnitude (CMM) of the log-likelihood ratio messages at the output of each decoding iteration. Information-theoretic support and extensive simulations are provided to demonstrate the efficiency of the criterion
