On fading margin in ultrawideband communications over multipath channels

This work studies ultra wideband (UWB) communications over multipath residential indoor channels. We study the relationship between the fading margin and the transmitter-receiver separation distance for both the line of sight and the no line of sight scenarios. Impairments such as small scale fading as well as large scale fading are considered. Some implications of the results for UWB indoor network design are discussed.
