On transmitted-reference UWB communications

In this paper we present a general framework for evaluating the exact performance of transmitted-reference (TR) signaling systems. Due to its simplicity, there has been a renewed interest in TR signaling for ultra-wide bandwidth (UWB) systems. This scheme has the benefit that it is robust in fast varying, highly selective fading channels, provided that the data and reference separation is on the order of the channel coherence. Using the framework provided, we evaluate the performance of UWB TR systems operating in arbitrary fading channels.
