Research of chaotic FH sequences generated by combined map

Based on the queuing theory, Logistic map and Tent map, a new method to generate chaotic FH sequences through mixed chaotic map is proposed in order to increase the linear complication of chaotic FH sequences and boost up the anti-prediction. The simulation results show that the FH sequences presented not only improve the anti-prediction of the system, but also have an ideaI balance, Hamming correlation and FH distance. Moreover, a variety of sequences can be easily implemented.
