摘要
针对混沌信号具有伪随机性、类噪声以及对初始条件的极端敏感性的特点 ,用定点算法有效地产生了数字混沌序列 ,着重分析了 L ogistic数字混沌序列的相关性能 ,得到了序列长度对相关性能的渐近关系式 ,并与模拟混沌序列的相关性能进行了比较 ,仿真结果表明用定点算法产生的数字混沌序列具有与模拟混沌序列一样的相关特性 ,数字量化并没有破坏混沌序列的特性。
A new method is advanced for generating binary chaotic sequences by means of integer arithmetic. We analyzed the correlation property of digital chaotic sequence by logistic maps and compared it with the simulative chaotic sequence. From the statistics,we got its approximate formula and found find that the length of sequences has a very important influence on the correlation property . Finally, the simulation results are presented .
