Error Probability of Chaotic Sequences Using Chaotic Quantification in CDMA System

When chaos is applied in practical communication system, there exits the finite problem, and the linear quantification has poor security property. To solve these problems, a new nonlinear method of chaotic quantification is introduced. And the bit error property in CDMA system which uses this method and involves AWGN, multipath and fading is studied. Based on Monte Carlo method, the simulation results are given to show that the sequence generated by chaotic quantification has ideal property and is suitable for practical use.
