Detection of Physics-Based Ultra-Wideband Signals Using Generalized RAKE in Presence of Inter-Symbol Interference

Abstract

The generalized rake receiver based on physics-based channel model is proposed for UWB outdoor application to estimate and compensate for the pulse distortion. The successive channel estimation is adopted to generate the per-path waveform as the template for the generalized rake receiver. The receiver can eliminate the effect of pulse distortion appearing in a lot of UWB channels. MMSE linear equalizer is used to handle intersymbol interference (ISI) for achieving high data rate
