| 摘 要： | 混沌通信具有硬件实现低复杂度、低功耗和抗多径等特性,成为低速超宽带通信和无线传感网的候选方案.在各种混沌通信方案中,调频差分混沌键控因采用易于实现的非相干解调成为了研究的热点.本文提出一种新的增强型调频差分混沌键控通信系统,对每比特采样点数、每符号比特数和信号占空比对于系统性能的影响进行了分析,通过仿真证明了理论分析的正确性.

| Abstract: | Due to the low complexity in hardware implementation,low power consumption and robust in multipath environment of chaotic communication,chaotic communication is one of the possible candidate signals,applicable to both low rate Ultra Wide Band(UWB) systems and wireless sensor networks.Among the modulation schemes using the chaotic signal,Frequency Modulation Differential Chaos Shift Keying(FM-DCSK) is a robust non-coherent technique with respect to the implementation issue and much research effort has been d... |
