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。

This paper proposed a method of blind identifying of the length of linear block code based on the run interval feature.Firstly,the distribution of run interval was obtained through counting the number of run inter-val under the fixed run length.After that,the period length was extracted from the distribution of run interval so that to get the length of linear block code.Simulation results showed that the proposed method had some strong points such as high robustness ,fast effectiveness and accurate recognition,and which was indicated that the method had a certain valuable application in future engineering fields.
