Executive Summary

This paper presents an analysis of the performance of a baseband Multiple-Input Single-Output (MISO) Time Reversal Ultra-WideBand system (TR-UWB) incorporating a symbol spaced Decision Feedback Equalizer (DFE). A semi-analytical performance analysis based on a Gaussian approach is considered, which matched well with simulation results, even for the DFE case. The channel model adopted is based on the IEEE 802.15.3a model, considering correlated shadowing across antenna elements. In order to provide a more realistic analysis, channel estimation errors are considered for the design of the TR filter. A guideline for the choice of equalizer length is provided.
