交织长度的识别是交织器识别过程中重要的步骤,关系到纠错码识别和信息的获取,具有重要的研究价值。文中简要介绍矩阵分析法,针对矩阵分析法容错能力不强的缺点,借助码重分布的概念,提出利用块重分布识别低码率二进制线性分组码序列交织长度的方法。最后,对两种方法进行仿真对比,分析了各自的适用范围和容错能力。
交織長度的識彆是交織器識彆過程中重要的步驟,關繫到糾錯碼識彆和信息的穫取,具有重要的研究價值。文中簡要介紹矩陣分析法,針對矩陣分析法容錯能力不彊的缺點,藉助碼重分佈的概唸,提齣利用塊重分佈識彆低碼率二進製線性分組碼序列交織長度的方法。最後,對兩種方法進行倣真對比,分析瞭各自的適用範圍和容錯能力。

The identification of the interleaver length is an important step in the process of interleaver identification. It is related to the identification of error-correcting codes and the obtainment of intercepted information. So it is necessary to study this issue. The method of matrix analysis is introduced. Against to the low tolerance of matrix analysis, the method of weight distribution is proposed to identify the length of interleaver based on the sequence of low code-rate binary linear block cedes. Finally, the two methods are simulated and compared for the scope and fault tolerance analysis.
