Method of chaotic pulse sequence produced by continuous chaotic system

Based on chaos theory, method of producing chaotic pulse sequence by chaotic phase trajectory with pseudo-randomness is proposed. Chaotic pulse sequence is generated with continuous chaotic system, and such problems as simple model, short period, digital degradation and easy tracking in chaotic sequence models produced by ordinary discrete chaotic systems are solved. The chaotic sequence generated by the presented method can be used in secure communication to enhance pseudo-randomness of the chaotic encryption key and attain infinite period. The simulation result proves the feasibility of the proposed method.
