| Abstract: | Based on the combination of Logistic map and Hybird map, a method with combined
map to generate chaotic frequency hopping(FH) sequences is proposed i
n order to enhance the properties of secrecy and security in traditional FH sys
tems.The properties of new sequence are simulated including initial sensitivity,
balance and Hamming correlation. Simulation results show that the new chaotic F
H sequence can easily overcome the problem of finite precision effect, besides,
it has higher initial sensitivity, better Hamming correlation property and highe
r balance property. |
