| Abstract: | 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. |
| Keywords: | Chaos Logistic map Spreading sequence Even and odd correlations |
