Correlation and Capacity Calculations with Reference Antennas in an Isotropic Environment
International Journal of Antennas and Propagation, 2012 A reverberation chamber is a convenient tool for over-the-air testing of MIMO devices in isotropic environments. Isotropy is typically achieved in the chamber through the use of a mode stirrer and a turntable on which the device under test (DUT) rides ...

Acoustical Modeling of Reverberation Chambers [PDF]
The Journal of the Acoustical Society of America, 1970 Critical listening tests conducted in full-scale reverberation chambers utilized in the recording industry reveal that there are often two major faults present in the decay of sound in the frequency range below 1000 Hz: (1) prolonged decay of certain axial modes resulting in a characteristic tone imparted to program materials; (2) beating between the ...
