A reconfigurable impulse radio ultra-wideband (UWB) pulse generator for various UWB shapes (e.g., monocycle, doublet, and triplet pulses) based on a nonlinear optical loop mirror (NOLM) and differential detection is proposed and experimentally demonstrated. The proposed approach can be used with different modulation formats and may be suitable for implementation in future low-cost, high-speed, ...

The application of ultra-wideband (UWB) technology to low-cost short-range communications presents unique challenges to the communications engineer. The impact of the US FCC’s regulations and the characteristics of the low-power UWB propagation channels are explored, and their effects on UWB hardware design are illustrated. This tutorial introduction includes references to more detailed explora...

Research in the design of ultra-wideband (UWB) radio systems suggests di erent kinds of signal design criteria. After an introduction to UWB radio, a variety of sequence design problems, motivated by UWB system constraints, will be presented. Design for time-hopping, for spectral atness, for rapid acquisition, and for multiple access will be discussed, and some sample designs will be presented.

Wireless communication technology has given us convenient ways to transfer information from one point to other anywhere in the world. The recent popularity of wireless networks results in many additional requirements of the system, especially the need of high data rates, demand for high quality multimedia services and the requirement of the greater bandwidth. The Ultra Wideband (UWB) radio comm...

This paper demonstrates optimum receiver performance in terms of bit error rate (BER) for time hopping pulse position modulation (TH-PPM) ultra wideband (UWB) system in multiple user interference environment for indoor radio communication. Equal gain combining and selective gain combining have been demonstrated in terms of ideal RAKE (ARAKE), selective RAKE (SRAKE) and partial RAKE (PRAKE) rece...

Ultra-wideband (UWB) bandpass filters play a key role in the development of UWB systems. In this paper, we present a review on their development since the release of UWB band for indoor and hand-held systems by Federal Communications Commission (FCC) in 2002.

The aim of this document it to present an overview of some recent research activities on ultra–wideband (UWB) channel modeling. Compared to models introduced in DRB1.2, recent research was focused on more sophisticated tools to model UWB channels, like information theoretic arguments. Physical modeling of UWB channels was also investigated. Reference D.xx.xx Issue n.m 4 November 2006 507325 NEW...

This paper investigates the performance of the high speed 2-parallel MB-OFDM ultra-wideband (UWB) receiver. Achieving high speed and low complexity become a challenge of UWB system design. In our solution, a highspeed low-complexity 2-parallel MB-OFDM UWB system with fixed point data type will be described and simulated.

Recent advances in wideband impulse technology, low power communication along with unlicensed band have enabled ultra wide band (UWB) as a leading technology for future wireless applications. This paper outlines the applications of emerging UWB technology in a private and commercial sector. We further talk about UWB technology for a wireless body area network (WBAN).

In this tutorial paper, the basic principles of the ultra wideband impulse radio (IR-UWB) technology are covered.
