Research of chaotic fh sequences generated by combined map
混合映射混沌跳頻序列的研究In addition, hybrid spread - spectrum communication system is propitious to enhance anti - jamming performance of the system that is make up of direct sequence ( ds ) and frequency hopping ( fh ), and it can satisfy the require of anti - jamming of systems. it concentrate their virtue and overcome shortage in single spread spectrum style. this paper discusses the aspect in detail
另外,將擴頻技術中應用最廣泛的兩項技術直序擴頻( ds )和跳頻( fh )結合在一起,構成混合擴頻通信系統,有利於提高系統的抗干擾性能,更能滿足系統抗干擾的要求,而且將跳頻系統和直擴系統的優點集中起來,克服了單一擴頻方式的不足。( 2 ) a new digital frequency - hopping communication system based on cipher - quasi - chaotic sequence is proposed, which combines the cryptography and frequency - hopping technology. the system ' s protocol, base - band signal processing and modulation / demodulation algorithms of the radio - frequency part are designed, and the hardware experiment conducted on a prototype of the system show that the system functions well. the finite precision problem arising while taking use of chaotic signal to generate pseudo - random sequence is studied and the anti - tracking capability of the cipher - quasi - chaotic sequence is studied with the volterra - tls method proposed in this dissertation
