| 摘 要： | 为了获取数字通信中未知线路的自同步扰码信息，在对信源不平衡条件下自同步加扰序列的重码统计特性进行深入分析的基础上，提出了基于重码统计的自同步扰码多项式阶数盲测定方法。之后，基于组合不平衡性的思想，提出了一种优于Walsh变换法的自同步扰码多项式抽头位置判定算法。实验和仿真结果验证了理论分析的正确性和自同步扰码多项式盲恢...

| Abstract: | In order to get the self-synchronizing scrambling information of the unknown lines in digital communication,a novel method of blind detection of the order of self-synchronizing scrambling polynomial is proposed based on deeply studying the statistic characteristics of reduplicate codes in self-synchronizing scrambled sequence on condition that the number of 0 or 1 bit in source is imbalanced.Later,an algorithm for estimating the feedback position in self-synchronizing scrambling polynomial,which is better t... |
