摘要
对一种混沌序列码的构造作了简单说明.在此基础上,提出了一种改进的生成方案.仿真和数据测试表明,改进后的序列不仅保持了原有序列的优点,具有良好的随机性,周期也得到了显著的扩展.
In this paper, a brief description of a chaotic sequence-generating scheme is given. Based on an analysis of its properties, an improved method is presented. Computer simulations show that the properties of the modified sequence are greatly improved, and its period is greatly expanded.
