Performance Research and Analysis for Three Kinds of Chaotic Spread Spectrum Sequence

Shujuan Yu

Abstract

Using MATLAB simulation platform,the modeling and simulation of DS-CDMA system based on chaotic spread spectrum are carried out.In the situation of this system model,the simulation analyses are carried out for the balanced state,using three kinds of different chaotic spread spectrum sequences(Logistic,the balance of Tent,Chebyshev),and for error code performance of the corresponding CDMA spread spectrum communication system.The simulation result indicated that the choice of chaotic spread spectrum sequences has certain influence on the system performance.
