Ultra-wideband (UWB) communication link modeling and characterization

This paper introduces modeling of a ultra-wideband (UWB) communication link, using two monopole antennas, in terms of the singularity expansion method (SEM) via Prony´s method. Prony´s Method is used to extract poles and residues of the link. By obtaining the poles and residues of the link it is possible to construct a transfer function of the link in both time and frequency domains. This representation is a convenient way of characterizing and modeling a UWB communication system with a reduced number of parameters.
