Abstract
Transmitted-reference (TR) signaling, in conjunction with an autocorrelation receiver (AcR), offers a low-complexity alternative to Rake reception. Due to its simplicity, there is renewed interest in TR signaling for ultrawide bandwidth (UWB) systems. Different variations of TR signaling have been proposed and investigated, including differential TR (DTR) signaling and noise averaging at the AcR. This paper provides performance analysis of various TR schemes by developing an analytical framework based on the sampling expansion approach. Specifically, we derive uncoded bit error probability (BEP) of different TR signaling schemes such as DTR and noise averaging at the AcR for a broad class of fading channels.
