摘要

本文提出了一种新的turbo码译码算法，该算法通过迭代译码过程更新似然值和信道值，使其更接近真实值。提出了更新似然值和信道值的准则，这些准则是基于比较每个分量解码器的临时硬决策结果的简单方法。

Iterative decoding algorithms updating likelihood and channel values based on interim hard decision results

This paper presents novel decoding algorithms for turbo codes, in which the likelihood and channel values are updated in order for those values to become closer to the true values thorough the iterative decoding procedure. The criteria for updating the likelihood and channel values are proposed, those are based on the simple means to compare the interim hard decision results from each of component decoders.
