摘要：
In this paper, we analyze the performance of a particular class of Transmitted Reference (TR) receiver for Impulse Radio (IR) Ultra Wide Band (UWB) communication systems, which is called Chip Time Differential Transmitted Reference (T-c-DTR). The analysis aims at investigating the performance of this receiver in the presence of faded narrow band interference, and at comparing it with other TR receiver schemes proposed in the literature. It is shown that T-c-DTR receivers can offer a substantial performance gain with respect to other non coherent receiver architectures, provided that some optimization conditions on code design are satisfied. Guidelines for optimal code and system optimization to reject narrow band interference are provided in the present manuscript, as well as their effect on system performance. Numerical simulations are also shown to substantiate findings and analytical derivations.
