Problems solved by technology
The generation method of chaotic spread spectrum sequence based on dynamic multi-mapping composite, to cope with the limitation of the limited number of sequences and the fixed mechanism of chaotic communication, this method is proposed based on the research basis of the improved Logistic, Chebyshev, and Kent three mappings. Use the control parameters to select the odd map and the even map from the improved Logistic, Chebyshev, and use the Kent map to establish a fractal function, thereby driving the fractal parameters of the odd map and the even map, and then the output of the odd map drives the initial value of the even map, and the even map The output of drives the initial value of the odd map. The selection function is established through the association of the odd map and the even map, and drives the initial value of the Kent map. Thus, the final new sequence is output through the optimization function of odd and even maps. This method can provide more address codes for the spread spectrum communication system, thereby expanding the application of the communication system.
