Application and Research in DSSS Based on Chaotic Sequence

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.
