The study of multiple access technology mainly aims at reducing the complexity of receiver as to implement low power consumption and low cost, besides decreasing the multiple access interference as much as possible. In this paper, the multiple access performances of spread spectrum with chaotic sequence and that with pseudo - random sequence, pseudo - chaotic time hopping and conventional time hopping are compared, in terms of theoretical analysis of bit error rate, simulation results and the receiver. It is shown that, as the system bit error rate is concerned, pseudo- random sequence spread ...
