| 摘 要： | 伪随机序列在流密码、信道编码、扩频通信等领域有着广泛的应用.线性复杂度及其稳定性是序列伪随机性的重要度量指标.C Ding等给出了一类具有理想自相关性的周期序列,该序列的0-1分布是几乎均衡的.本文讨论了此类序列的其它伪随机性.本文的主要结果如下:此类序列具有令人满意的线性复杂度;在一个符号替换之下此类序列的线性复杂度不会退化.

| Abstract: | Pseudo random sequence has broad applications in stream cipher,channel coding,and spread spectrum communication.Linear complexity and its robustness are important features of pseudo randomness.C Ding presented a novel class of sequences with ideal autocorrelation and almost balanced 0-1 distribution.This paper discusses other pseudo randomness of such sequences.The major results are the following:such sequences have quite satisfactory linear complexities;their linear complexities do not degenerate under single symbol substitution. |

| Keywords: | pseudo random sequence stream cipher linear complexity robustness |
