Abstract

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 CE-based (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 we 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.
