Abstract

The Transmitted-Reference (TR) signaling scheme in conjunction with the Auto-corrrelation Reciever (AcR) has gained popularity in the last few years as low-complexity systems architecture for Ultra Wide Band (UWB) communications. Since the signal template used for the demodulation is directly obtained form the received signal not only the noise but also the interference caused by a narrowband (NB) system operating in the same bandwidth corrupt both the data and the reference pulses. In this paper we study the effects of single-tone interferer on the performance of a TR system, measured in terms of probability of error. We also propose to use a bank of notch filters for the detection and the suppression of the NB signal.
