A phase-based indicator for discriminating near LOS Reverberating Chamber channel conditions

In this paper a phased based indicator for discriminating the near Line-of-Sight (nLOS) channel conditions within a Reverberating Chamber (RC) is proposed. The kurtosis index, k, is first applied to the phase of the electromagnetic field especially to characterize regions in which obstacles obstruct the first Fresnel zone, i.e. the nLOS conditions. A large set of experiments accomplished at the RC of the Università di Napoli Parthenope, formerly Istituto Universitario Navale (IUN), confirm the effectiveness of the proposed parameter from an operational point of view.
