【摘要】：针对线性分组码的码长识别问题,提出了一种基于游程间隔特征的线性分组码码长识别方法。该方法通过统计不同游程长度下游程间隔的数量得到游程间隔的分布特征,从中提取出具有周期特性的游程间隔的周期长度,实现对线性分组码码长的识别。仿真结果验证了算法的有效性和鲁棒性,表明本文算法比已有算法具有更好的抗误码性能和一定的工程应用前景。
[Abstract]:In order to solve the problem of code length recognition of linear block codes, a linear block code length recognition method based on run-time interval features is proposed. In this method, the distribution characteristics of run-time intervals are obtained by counting the number of run-time intervals with different run lengths, and the periodic length of run-time intervals with periodic characteristics is extracted from them to realize the recognition of the code length of linear block codes. The simulation results verify the effectiveness and robustness of the proposed algorithm, and show that the proposed algorithm has better error-resistant performance than the existing algorithms and has a certain prospect of engineering application.
