Abstract: The initial value sensitivity, balance properties and correlation properties of chaotic sequences based on Chebyshev mapping are studied. Performance of chaotic sequences is compared with Gold sequences in DS-CDMA system. Simulation results show that chaotic sequences have approximately the same correlation properties as Gold sequences. As an ideal choice, it is easy to generate a large number of chaotic sequences with good security.
