作为一种热门的短距离无线通信技术，超宽带通信具有宽信号频带范围和低功率谱密度等特点，能够在传统窄带通信已占用的频带上进行通信而不会引发较大干扰，这在通信频谱资源日益紧张的今天意义显著。同时，作为一种本质的宽带载波，混沌信号具有利用简单电路即可产生，低成本扩频等特性，在超宽带通信系统的应用中具有潜在的优势。 FM-DCSKUWB（Frequency-ModulatedDifferentialChaosShiftKeyingUltra-Wideband，调频差分混沌位移键控超宽带）系统因其融合以上两种技术的特性，在低速、低功耗的WPAN（WirelessPersonalAreaNetworks，...Abstract As a popular technology in short-range wireless communication, ultra-wideband (UWB) transmission with wide band spectrum and low power spectral density can be implemented under the spectrum range occupied by traditional narrow band communication systems but only causing little interference. This new way of reusing assigned spectrum is very important especially in the context of scarce s...学位：工学硕士院系专业：信息科学与技术学院通信工程系_通信与信息系统学号：X200622400
