A Systematic Study: Channel Sounding via Modal Expansion



Alex Yuffa, Ben Jamroz, Jake Rezac, Dylan Williams


We present preliminary results of using a modal (partial wave) expansion of the field to characterize a propagation channel. We assume that the measurements of the scalar, two-dimensional field from which the modal expansion coefficients are obtained contain Gaussian phase noise with zero mean. Three spatial sampling patterns of the field are considered. It is found that the accuracy of the reconstructed field is strongly influenced by the spatial sampling pattern.
