Abstract
In Ultra Wideband (UWB) wireless systems, multipath components have different waveforms depending on the used antennas and the angles of transmission and reception. Multi-template subtractive deconvolution is modified and applied to an extensive channel measurement campaign. The modified algorithm utilizes the variation on the waveforms to extract the directional UWB channel response. Directional characterization of UWB channels facilitates performance evaluation studies and allows for more accurate positioning and imaging. The use of subtractive deconvolution rather than zero-insertion used by previous authors allows for resolving overlapping components and hence improves the energy capture in Rake receivers.
