摘 要
隨著無(wú)線通信技術(shù)的高速發(fā)展，人們對(duì)無(wú)線通信系統(tǒng)的要求日益提高，超寬帶（Ultra-Wideband，UWB）技術(shù)憑借其高速率的數(shù)據(jù)傳輸、極低的功耗以及其精準(zhǔn)的定位等性能，逐漸成為無(wú)線通信領(lǐng)域研究的一個(gè)熱點(diǎn)，受到了廣泛的關(guān)注。
本文首先介紹了超寬帶（UWB）技術(shù)的歷史背景及其定義和特點(diǎn)。其次針對(duì)超寬帶（UWB）的原理及其波形進(jìn)行了研究和探討。然后論述了超寬帶（UWB）的調(diào)制與接收，并主要分析了PPM-TH-UW，PAM-DS-UWB，MB-OFDM-UWB這三種調(diào)制方式。最后本文重點(diǎn)介紹了超寬帶（UWB）的無(wú)線定位技術(shù)，首先是對(duì)其發(fā)展和定義進(jìn)行了概述，其次分別介紹了超寬帶無(wú)線定位的參數(shù)及其幾何模型，重點(diǎn)對(duì)UWB定位中TOA的算法進(jìn)行了研究，最后通過(guò)仿真對(duì)定位算法的實(shí)現(xiàn)做出了驗(yàn)證并得到了重要結(jié)論。

Abstract
With the rapid development of wireless communication technology, the wireless communication system of the increasing demand, ultra wideband (Ultra-Wideband, UWB) technology by virtue of its high data rate, low power consumption and its precise positioning performance, has become the field of wireless communication research a hot spot, has received the widespread attention.
This thesis first introduces the ultra wideband (UWB) technology to the historical background and the definition and characteristics of. Secondly, ultra wideband (UWB) principle and waveform are studied and discussed. And then discusses the ultra wideband (UWB) modulation and receiving, and primary analysis of PPM-TH-UW, PAM-DS-UWB, MB-OFDM-UWB the three modulation methods. Finally, this thesis introduces the ultra wideband (UWB) wireless positioning technology, first of its development and definition are outlined, followed by introduces UWB wireless positioning parameters and geometry model, focus on the localization of UWB TOA algorithm is studied, finally through the simulation of positioning algorithm to verify and obtained important conclusion.
Key words: ultra wideband (UWB), wireless positioning technology.
Type of thesis: theoretical research
