Abstract: Ultra Wideband (UWB) radio is one of the emerging technologies which have promising characteristics such as high data rate transmission, material penetration, multiple access capability and reduced fading. It has the potential to evolve as the future solution to high data rate short range wireless communication, and other applications including imaging and radar. This research aims to establish a comprehensive database, performance verification of the existing channel models, and a proposal of new channel models. This research contributes further to the channel characterization of the UWB channels and proposes a new model with enhanced statistical description using a large database of indoor and outdoor UWB measurements. The existing channel models are inadequate to study the delay characteristics of the UWB channel. The proposed model has new information regarding statistical descriptions of channel delay characteristics, including mean excess delay and root mean square (RMS) delay spread.
