Abstract

In this paper, a novel optimized selection algorithm based on the balance and correlation is proposed to improve the performance of chaotic PN sequences when an integrated chaotic spread-spectrum sequences and its performance are analyzed. In the optimized selection algorithm, a threshold is introduced to keep the sequences balance and minish the auto correlation. The computer simulations confirm that the proposed selection algorithm provides good BERs in multi-user direct sequence code division multiple access (DS-CDMA) based on the chaotic communication systems.
