摘要
本文根据符号动力学,利用混沌系统构造了一族相互独立的Bernoulli序列作为扩频序列,给出了获得q元Bernoulli序列的一种设计准则——测度熵等于logq。
A criterion for designing chaotic spreading sequences based on symbolic dynamics is proposed. A family of mutually independent Bernoulli sequences can be generated by this approach. A condition for the metric entropy to obtain q-ary Bernoulli sequences is proved.
