Ultra-wideband (uwb) communication link modeling and craracterization
IEEE Conference on Ultra Wideband Systems and Technologies, 2003, 2004This paper introduces modeling of a ultra-wideband (UWB) communication link, using two monopole antennas, in terms of the singularity expansion method (SEM) via Prony's method. Prony's Method is used to extract poles and residues of the link. By obtaining the poles and residues of the link it is possible to construct a transfer function of the link in ...

Ultra-wideband (UWB) channel dispersion: classification and modeling
2005 IEEE Antennas and Propagation Society International Symposium, 2005In this paper, UWB communication system dispersive phenomena has been investigated, which are divided into three types: frequency, resonant, and multipath dispersion. Existing wideband channel models are extended by incorporating dispersion mechanisms that have not been previously considered.

A Novel Ultra Wideband Antenna for UWB Applications
2007 Loughborough Antennas and Propagation Conference, 2007In this paper, a new ultra-wideband (UWB) antenna for UWB applications is proposed. The presented antenna is designed to operate from 1.8 to 12 GHz. Regarding high bandwidth, antenna size and commercial aspects in design procedure, the manufacturability of antenna is considered also.

Time Reversal for Ultra-wideband (UWB) Sensor Networking
2007Abstract : This report organized into six chapters. It addresses coupling effects, an analysis of the virtual array, single-user and multi-user time reversal UWB-MIMO system performance, and a comparison with time reversal UWB-MISO. The central topic of this report is to experimentally study the multiusers MIMO with time reversal transmission.

Ultra-wideband (UWB) incidence on multiple dielectric interfaces
IEEE Antennas and Propagation Society Symposium, 2004., 2004The problem of a pulsed short-duration ultra-wideband (UWB) electromagnetic field incident on a multiple-layer lossy dielectric wall is considered. The electromagnetic fields are computed utilizing both frequency-domain (FFT) and finite-difference time-domain (FDTD) formalisms.

Electro-magnetic imaging with ultra-wideband (UWB) sensors
2020Both the multi-step and singe -step solutions to UWB inverse scattering problem are first discussed in this chapter. In the former, the CDF-Broyden update using the refined Polak-Rebiere's non -quadratic approximation will be focused. Meanwhile, the enhanced delay and sum (EDAS) algorithm, which uses the coherence factor and multiply in pair will be ...

Ultra-Wideband (UWB) Wireless Communications: A Tutorial
2003Ultra wide band (UWB) radio has recently attracted increased attention due to its expected unlicensed operation, and potential to provide very high data rates at relatively short ranges. In this article we briefly describe some main candidate multiple access and modulation schemes for UWB communications, followed with their power spectral density ...
