A Novel Selective Transmitted Reference Transceiver for High Data Rate UWB

The transmitted reference (TR) receiver provides a good alternative to the good-yet-expensive RAKE receiver for ultra wideband impulse radio (UWB-IR). TR receiver is however inefficient due to the necessity in transmitting a reference prior to the data symbol. In this paper, the performance of TR receiver is investigated under high data rate transmission and compared to that of RAKE receiver. It is shown that the performance of basic TR is worse than a fractionally spaced selective RAKE receiver. A simple selective TR transceiver is then proposed to improve the performance of TR under ISI. It is shown that the proposed approach achieves almost similar performance to that of selective RAKE receiver while still maintains the simplicity of TR.
