The principle of multi-user chaotic sequence spread-spectrum communication system is introduced. Performances of balance and correlation properties of three different chaotic spread series (Chebyshev, Logistic and Tent) are analyzed. The dynamic visual simulation modeling of multi-user chaotic sequence spread-spectrum communication system is established. Based on this modeling, the error-bit rate performances of these systems with different initial values, signal to noise ratio, number of users and the length of sequence are investigated. Simulation results show that the spread-spectrum performance of Chebyshev is the best, then Logistic and Tent, and the spread-spectrum performances of the three chaotic spread series are better than that of the conventional spread sequence.
