Abstract :
A four-dimensional super-chaotic system is introduced in this paper. With the analysis of the dynamic of the system, it can be drawn that the Lyapunov index is very high. Based on the system, a new spread spectrum sequence with good balance, correlation and is generated. Not only the chaotic system itself is very complicated, but also the generation of the sequence is complex, which leads it to be very applicable for information security. Experiment results demonstrate that this spread spectrum sequence has excellent anti-MAI performance and improves the information security of system when applied into the DS-CDMA, thus, it is very suitable for DS-CDMA system.
