The Reverberating Chamber as a Line-of-Sight Wireless Channel Emulator

The reverberating chamber (RC) is employed to physically emulate line-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 objectively 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.
