Multi-user perspectives in UWB communications networks

Abstract

Ultra-wideband technology provides robust high data rate networks that can be used to meet the needs of wireless personal area network (WPAN) applications. An essential part of this design is the selection of a multiplexing technique to provide multiple physical channels (piconets) from the single shared UWB band. This paper provides an overview of multiplexing techniques and suggests ways in which they can be applied to UWB networks. Relative advantages and challenges of each technique are identified in order to understand the suitabilitity of each for use in a multi-piconet WPAN system.
