| Abstract: | Anew chaotic sequence based on Tent-map is proposed in this paper. The method of generating the Tent-map digital chaotic sequences is analyzed. Through analyzing the digital chaotic sequence applied in direct sequence spread spectrum communication system and Simulink simulation,the results show that the new digital chaotic sequence,which meets sperformance requirements of spread spectrum communication system,has better transmission characteristics. |
