Abstract: The current research on the generation of frequency hopping(FH) sequences based on chaotic map is investigated.And then,the limitation of FH sequences generation based on Logistic is analyzed by use of state shift map.Furthermore,an improved scheme of FH sequences based on phalanx is proposed by using the related theory of random process.It has been proved that the FH performance of the scheme is equal to or even better than the primary scheme.More over,the multiply times of the redesigned method can be reduced in hardware realization with decreased occupation of hardware resources,and the implement probability of FH sequences can be increased.
