Development of a Novel Measurement Technique for Emulating Real Life Environment within a Semi Reverberating Chamber

Abstract

In this paper, the most important compact descriptors of wireless propagation channels, i.e. the power delay profile (PDP), the root mean square delay spread $\tau_{\rm{rms}}$ and the probability density function (pdf) of the field amplitude, are emulated with a novel reverberating chamber (RC) measurements method. In particular, the semi reverberating chamber (SRC) is obtained by simply realizing two anechoic corners within the RC. Experiments conducted by employing the RC of the Università degli Studi di Napoli Parthenope, formerly Istituto Universitario Navale (IUN), on the PDP, $\tau_{\rm{rms}}$ and pdf of the field amplitude, have been compared with theoretical expectation. Furthermore, measurements of multipath channel in a typical working environment, i.e. the IUN research laboratory, are made. Comparisons among the emulated compact parameters and the ones of real life environments, i.e. IUN electromagnetic laboratory, show the soundness of the new proposed technique.
