| 本文介绍了Turbo码中迭代译码的两种新的迭代终止准则，并通过仿真研究了这两种迭代终止准则的性能。这两种迭代终止准则都是基于互熵（CE）的概念，但是后一种比CE准则更简单，具有更低的计算复杂度。 |

| Stopping Criterion for Iteration Decoding of Turbo Codes |
|
| () |
| Abstract: |
| This paper introduces two new kinds of effective criterion for stopping the iteration process in turbo decoding, studies the performance of two stopping criterions. Both stopping criterions are based on the cross-entropy concept (CE), but the new criterion is simpler than CE criteria and can be realized with lower complexity. |
