An electronically reconfigurable reverberation chamber for the emulation of severe multipath channels

This paper covers the design of a new bench-top environment for testing wireless systems under severe multipath conditions. Reverberation chambers, upon which this design is based, have used a moving ´stirring blade´ to create multiple multipath channels. In this work, a set of electronically-controlled interference antennas is also used to develop multipath scenarios including newly demonstrated hyper-Rayleigh conditions. In addition, the work discusses correlations between severe fading and S₂₁ group delay.
