Abstract

In this paper, chaotic sequence is produced by Logistic map. The sensitivity of initial value, relevance and run length are analyzed. Chaotic sequence and m sequence are compared in the DS-CDMA communication system in elimination multiple access interference and overcoming the noise. Simulation results show that chaotic sequence is a new spread-spectrum code after m sequence and Gold sequence and so on, because it has many features, such as numerous, simple in implement, abundance of the source of code.
