Simulink Spread Spectrum Communication and Performance of Multi-Access Based on New Chaotic Sequence

Wan C. Kan

Abstract

A novel improved Bernoulli chaotic map is proposed according to reconstruction principle for better performance of chaotic spread spectrum sequence. The new map has a weak structure. Then the multi-user spread spectrum communication system is constructed by Simulink. Anti-multiple access capability of the chaotic sequence generated by the improved map and the Bernoulli map is analyzed. Simulation results show that new chaotic sequence has the better ability against noise and multiple access interference than the Bernoulli sequence.
