Research on Key Techniques of Digital Iterative Receive for M-ary Differential Chaos Shift Keying Modulation System

Abstract

以近似噪声的混沌信号为载波的混沌调制方式因其利用了混沌信号所具有的一些固有特性,如高自相关和低互相关的特性,以及宽带特性,使得混沌通信系统在对抗多径干扰、安全通信以及与现存窄带通信系统共存性方面具有优异的表现。因此,作为超宽带(Ultra-Wideband,UWB)技术的一种参选调制方案,混沌调制方式能够与UWB技术一起在以无线体域网(WirelessBodyAreaNetwork,WBAN)为代表的众多功率受限系统中得到应用,为这些系统提供高速、可靠的通信服务。本文以提高多元差分混沌移位键控(M-aryDifferentialChaosShiftKeying,M-aryDCSK)系统的通信可...Due to the inherent characteristics of chaos signal, such as wideband spectra, high auto-correlation and low correlations between different signals, chaotic communication systems which use noise-like chaotic signals as the carrier, have strong anti-inference ability for multi-path fading and high communication security. Moreover, they also can co-exist with other conventional narrowband communicat...学位:工学博士院系专业:信息科学与技术学院_电路与系统学号:2312011015408
