Ultra-Wideband Radio Propagation Channels: A Practical Approach

Description

Ultra Wide Band (UWB) technology consists of transmitting radio signals over frequency bandwidths from 500 MHz to several GHz. Its unique characteristics may be exploited for the design of high data rate wireless communication systems, as well as localization and imaging applications. The development and optimization of such systems require a precise knowledge of the radio transmission medium. This book examines all aspects of the propagation channel for UWB systems. UWB technology is first presented, with a particular emphasis being placed on its applications, spectrum regulation issues, and the different communication techniques. The authors introduce the theoretical bases of radioelectric propagation and give an overview of the channel sounding techniques adapted for UWB signals. The two main principles of UWB channel modeling are finally exposed and illustrated: deterministic channel modeling, based on the simulation of the propagation phenomena in a given environment, and statistical channel modeling, which relies on the experimental analysis of the main channel characteristics.Content: Chapter 1 UWB Technology and its Applications (pages 21–42): Chapter 2 Radio Wave Propagation (pages 43–65): Chapter 3 UWB Propagation Channel Sounding (pages 67–98): Chapter 4 Deterministic Modeling of the UWB Channel (pages 99–131): Chapter 5 Statistical Modeling of the UWB Channel (pages 133–176): Chapter A Baseband Representation of the Radio Channel (pages 177–179): Chapter B Statistical Distributions (pages 181–187): Chapter C Geometric Optics and Uniform Theory of Diffraction (pages 189–208): Chapter D Ray Construction Techniques (pages 209–211): Chapter E Description of the Time?Frequency Transform (pages 213–218):
