Ultra-wideband Systems: Review

Main Article Content

Wilaiporn Lee


Nowadays, the demand for higher capacity, faster service, and more secure wireless connections increases, new enhanced technologies have to find their place in the overcrowded and scarce radio frequency (RF) spectrum. This is because every radio technology allocates a specific part of the spectrum; for example, the signals for TVs, radios, cell phones, and so on are sent on different frequencies to avoid interference to each other. As a result, the constraints on the availability of the RF spectrum become stricter with the introduction of new radio services. Ultrawideband (UWB) technology offers a promising solution to the RF spectrum drought by allowing new services to coexist with current radio systems with minimal or no interference. This coexistence brings the advantage of avoiding the expensive spectrum licensing fees that providers of all other radio services must pay. This article reviews the some basic knowledge of UWB systems including definition, transmitter, channel model and receiver of UWB systems. Moreover, we discuss the literature of three interesting topics, including pulse shape design, timing jitter and localization of UWB systems.
