Comments on "A New Parity-Check Stopping Criterion for Turbo Decoding"

A Parity-Check Stopping (PCS) criterion for turbo decoding is proposed in, which shows its priority compared with the stopping criteria of Sign Change Ratio (SCR), Sign Difference Ratio (SDR), Cross Entropy (CE) and improved CEbased (Yu) method. But another well-known simple stopping criterion named Hard-Decision-Aided (HDA) criterion has not been compared in. In this letter, through analysis the authors show that using max-log-MAP algorithm, PCS is equivalent to HDA; while simulations demonstrate that using log-MAP algorithm, PCS has nearly the same performance as HDA.
