Abstract :
A chaotic map model with infinite collapses in the finite region is proposed in this paper. The scheme of generating chaotic signals from this model is analyzed. Lyapunov exponents of the map calculated indicates that it has good properties of chaos. The CDMA spreading sequences produced by the model can achieve better autocorrelation and crosscorrelation characteristics than Gold sequences usually used
