Ultra-wideband (UWB) communications systems: an overview

Abstract

This paper presents an overview of the ultra-wideband (UWB) technology for wireless communications systems. Following a brief review of the UWB basic principles, the characteristics of application specific UWB wireless systems are described. Design principles and challenges of UWB wireless systems, with an emphasis on monolithic implementations are discussed. Trade-offs between performance, power consumption, and technology choices are addressed. Examples of state-of-the-art UWB circuits and systems are presented.
