一种新颖的Turbo码MAP译码器

摘要

根据Turbo码trellis结束的情况及Turbo码的特征本文提出了一种新的Turbo码MAP译码器，这是基于MAP译码器中两个组成译码器性能的不一致所作改进。从分析和仿真结果我们可以看到该方法的优势。%According to the trellis termination and the feature of Turbo codes a novel MAP decoder structure for Turbo codes is purposed. It' s due to the unequal error correcting capability of the two component decoders. The analysis and simulation results are presented to show its better performance
