论文摘要
在[1]中提出了用于涡轮解码的奇偶校验检查（PCS）标准，该标准与符号变化比（SCR），符号差异（SDR），交叉熵（CE）和改进的CEBATED（YU）方法相比，它显示了其优先级。但是，在[1]中尚未比较另一个著名的简单停止标准（HDA）标准（HDA）标准。在这封信中，通过分析我们表明，使用Max-Log-Map算法，PC相当于HDA。虽然模拟表明使用日志映射算法，但PC的性能与HDA的性能几乎相同。
A parity-check stopping (PCS) criterion for turbo decoding is proposed in [1], 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 [1]. 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.
