Abstract
With the rapid development of munication technology, the munication 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 e the field of munication 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
