A compact, reconfigurable chamber for emulating severe multipath fading

This paper details a compact, reconfigurable channel emulator (CRCE) specifically designed to create severe, multipath fading channels. The CRCE is a chamber that, unlike anechoic or reverberation chambers, provides non-uniform fading profiles for wireless devices placed within. In particular, the contribution of this work is that the CRCE is capable of creating not only Ricean and Rayleigh fading profiles, but also hyper-Rayleigh fading which is found in airframes and similar cavity structures. The CRCE enables such fading to be created in the laboratory and in a repeatable fashion.
