Ultrawide bandwidth transmitted-reference signaling

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 systems for UWB systems. To assess the performance of such systems, we develop an analytical framework based on a sampling expansion approach. In particular, we derive closed-form expressions for the exact SEP of TR systems with AcR that can be used to exploit multipath diversity inherent in wideband channels. We further extend the SEP derivation to include noise averaging. Our methodology does not require the Gaussian approximation and is applicable for any fading scenario given that the correlator output signal-to-noise ratio can be characterized by a moment generating function.
