Comparison of transmitted- and stored-reference systems for ultra-wideband communications

Abstract

Performance of a transmitted-reference system (TR) with a cross-correlation receiver is compared with that of a stored-reference system (SR) with a Rake receiver for ultra-wideband (UWB) communications. The effect of channel estimation error that appears in SR systems is taken into account, eliminating some unfair advantage in comparisons with TR systems. Some insight on system design for multipath channels is drawn from the comparison.
