Abstract

In this letter, we analyze the delay probability of the first error position in perturbation-enhanced Successive cancellation (SC) decoding for polar codes. Our findings reveal that, asymptotically, an SC decoder’s performance does not degrade after one perturbation, and it improves with a probability of

$\frac {1}{2}$

. This analysis explains the sustained performance gains of perturbation-enhanced SC decoding as code length increases.

扰动增强SC解码器的性能分析

在这篇文章中，我们分析了扰动增强连续抵消（SC）译码中第一错误位置的延迟概率。我们的研究结果表明，SC解码器的性能在一次扰动后不会逐渐下降，并且以$\frac{1}{2}$的概率提高。这一分析解释了扰动增强SC解码随着代码长度的增加而持续的性能提升。

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
