Abstract

High-resolution time-domain ultra-wideband (UWB) channel characterization with CLEAN deconvolution has become increasingly popular. However, due to the extremely wide bandwidth of the pulse, the assumption of negligible pulse distortion no longer holds. In this paper, we first summarize the current works in channel characterization with the CLEAN algorithm. We then show the a priori dependence of CLEAN, and propose a modified multi-template approach to overcome these issues while retaining its high-resolution capability.
