Error performance of pulse-based ultra-wideband systems in underground mines

Ultra-wideband (UWB) has attracted a lot of attention in the past few years. UWB offers several advantages over traditional narrow band. Transmitted reference (TR) receivers have been known for many decades, but there is a renewed interest in applications of TR receivers as a suboptimal solution for UWB communications because of the difficulty in estimating the channel accurately for an optimal solution. In this paper, the performance of a UWB-TR receiver in an UWB underground mine channel is evaluated. The performance at higher data rates in the case of inter-symbol interference (ISI) is also investigated.
