一类加随机扰动的Tent-Map数字混沌序列研究

Study of a class of Tent-Map digital chaotic sequence with random disturbances

提出了一类加随机扰动的Tent-Map,克服了周期性和不稳定性的缺点.用软件仿真,研究了所加随机扰动的幅度对数字混沌序列特性的影响.结果表明,随机扰动的幅度只有达到合适的值,才能得到性能优良的扩频码.

In order to overcome the shortcomings of periodicity and instability,a class of Tent-Map with random disturbances is proposed.Using soft simulation,this paper studies the magnitude of random disturbances added to the digital chaotic sequence,and gives magnitude range.The results show that only the magnitude of random disturbances is appropriate,the performance of chaotic spreading code can be good.
