Open publisher page 0 citations

Abstract

Chaotic sequence is considered as a good candidate for spread spectrum sequence in CDMA systems because it is characterized by good randomness, Kronecker Delta autocorrelation and orthogonal crosscorrelation. Through asynchronous CDMA system model, the authors analyze the key points of chaotic spread spectrum CDMA system performances,choose Chebyshev map to instantiate the virtue of chaotic sequences and compare with the classic Gold and Kasami sequences.
