摘要

本文提出了一种新的双二进制turbo码停止判据。随着迭代译码性能的提高,两个比特级外部信息之间的相关性增加。该方法为双二进制turbo码的符号级译码提供了一种更为合理的解决方案。仿真结果表明,与传统准则相比,该准则能够减少平均迭代译码次数,并具有良好的误码性能。

A New Stopping Criterion for Duo-binary Turbo Codes
This paper describes a novel stopping criterion for duo-binary turbo codes. The correlation between the two bit-level extrinsic information increased as the performance improved by the iterative decoding. In this way, the new method reflects a more reasonable solution for symbol-level decoding of duo-binary turbo codes. Simulation results showed that the proposal criterion was able to reduce the average iterative decoding number with a good error performance as compared to conventional criteria.
