针对信息截获领域中Turbo码识别问题,提出了一种基于矩阵分析的Turbo码长识别算法。简述了Turbo码编码和归零的基本原理,深入分析了Turbo码第1路、第2路、第3路和整体的生成矩阵,得出其本质上是一种线性分组码。将线性分组码的码长识别方法引入到Turbo码识别当中,并对算法进行了改进。仿真实验表明,此方法在较高的误码率基础上有着良好的识别效果。
針對信息截穫領域中Turbo碼識彆問題,提齣瞭一種基于矩陣分析的Turbo碼長識彆算法。簡述瞭Turbo碼編碼和歸零的基本原理,深入分析瞭Turbo碼第1路、第2路、第3路和整體的生成矩陣,得齣其本質上是一種線性分組碼。將線性分組碼的碼長識彆方法引入到Turbo碼識彆噹中,併對算法進行瞭改進。倣真實驗錶明,此方法在較高的誤碼率基礎上有著良好的識彆效果。
