摘要

利用平均可靠度(定义为对数似然比绝对值的平均值)，提出了一种新的并行串联turbo码设计方法。这个标准允许我们描述组成解码器的行为，并且进一步预测大块长度的迭代解码器的行为。平均信度也可用作停止准则。

Using the mean reliability as a design and stopping criterion for turbo codes

By means of the mean reliability (defined as the mean of the absolute values of log-likelihood ratios), a new design of parallel concatenated "turbo" codes is proposed. This criterion allows us to describe the behavior of the constituent decoders and, furthermore, to predict the behavior of the iterative decoder for large block lengths. The mean reliability can also be used as a stopping criterion.
