Research on Spreading Sequences with Chaotic Maps
一类混沌映射扩频序列的研究

Spreading sequence for Frequency Hopping(FH) sequence can be generated with logistic map. This paper constructs a second-order chaotic map based on logistic map, proves its probability density distribution, and proposes a method to generate chaotic frequency-hopping sequence. It also analyzes character of even and odd correlations by numerical simulation. The results shows the sequence has excellent properties.
