Abstract: The chaotic sequence is sensitively dependent on initial conditions and parameters of the chaotic system. This paper, firstly, presents a multiple access communications system model which is based on chaotic sequence; Secondly, introduces a chaotic circuit, and analyzes the multple access communication which is based on chaotic sequence; Finally, gives the simulation results which illustrated that chaotic sequence may become a good pseudo-random code to M sequence and gold sequence in the multiple access communications. -
