本文分析了扰动功率对延迟首个错误位置（即连续消除（SC）解码中首个错误解码的信息比特）的影响。研究在有限长度扰动增强型SC（PE - SC）解码范式下进行。结果表明首个错误位置延迟概率对扰动功率\(\sigma_{p}^{2}\)呈现非单调依赖关系。基于此特性，提出一种最大化延迟概率的有效扰动功率选择算法，以提高扰动效率，实现有限长度PE - SC解码中更高效的扰动功率选择。
英文摘要
In this paper, we analyze the effect of perturbation power in delaying the first error position, i.e., the first information bit incorrectly decoded by the successive cancellation (SC) decoding. It is conducted over the finite-length perturbation-enhanced SC (PE-SC) decoding paradigm. We show that the FEP delaying probability exhibits a non-monotonic dependence on the perturbation power \(σ_{p}^{2}\). Based on this property, an efficient perturbation power selection algorithm that maximizes the delay probability is proposed to enhance the perturbation efficiency. It results in a more efficient perturbation power selection in finite-length PE-SC decoding.
