The reverberating chamber as a line-of-sight wireless channel emulator

The reverberating chamber (RC) is employed to physically emulate fine-of-sight (LOS) propagation channels and to test the quality of a digital transmission. Use of different absorber configurations is able to generate various LOS propagation channels. The LOS channels are ob.. jectively characterized by the Rician K factor and results show that K is not generally dependent only on the number of absorbers but also on their configuration. Experiments are accomplished at the electrically large mode-stirred RC of the Universita di Napoli Parthenope, formerly Istituto Universitario Navale (IUN) and a Global System for Mobile Communications (GSM) digital signal is used.
