An effective indicator for NLOS, nLOS, LOS propagation channels conditions

A simple and physically-based index is proposed to identify among Line-of-Sight (LOS), near Line-of-Sight (nLOS) and Non-Line-of-Sight (NLOS) channel propagation conditions. The index is based on the Generalized K (GK) fading model which has been proven to embody different channel propagation conditions. Experiments undertaken over a large set of measurements accomplished by emulating different propagation channel conditions at the Reverberating Chamber (RC) of the Università di Napoli Parthenope (formerly Istituto Universitario Navale, IUN) confirm the soundness of the model and the effectiveness of the proposed index
