A new design of transmitted reference UWB transceiver with non-ideal delay lines

초록

The effect of group delay ripple (GDR) of nonideal delay line (DL) causes an unexpected type of distortion in transmitted reference (TR) ultra wide bandwidth (UWB) systems. In this paper, we propose a new TR transceiver structure, where the GDR information of DL at the receiver is introduced into the transmitter to mitigate the performance error due to the GDR. Through Monte Carlo simulation, it is proved that this new designed transceiver can greatly reduce the impact of nonideal DL with GDR on the performance of TR UWB systems.
