TL;DR: In this article, the authors show that the measurement accuracy can be significantly improved by rotating the antenna under test, which is referred to as platform stirring, and demonstrate in the 900 MHz GSM band by measurements in a reverberation chamber of dimensions 1.0 m×0.8 m×1.0m.

TL;DR: In this article, the relation between different parameters that characterize the reverberation chamber as a channel emulator for over-the-air (OTA) testing of wireless devices and components is investigated.

TL;DR: It is shown that the reverberation chamber emulates a rich isotropic multipath (RIMP), making it an extreme reference environment for testing of wireless devices, and a simple theory is presented that can accurately model measured throughput for a long-term evolution (LTE) system with orthogonal frequency-division multiplexing and multiple-input-multiple-output (MIMO).

TL;DR: The covariance eigenvalue approach and the embedded far field function method are presented to determine diversity gain and MIMO capacity for arbitrary multi-port antennas and there are in general good agreements between the reverberation and anechoic chamber measurement results.

TL;DR: In this paper, a numerical model of wires in rectangular metal cavities is introduced for computing antennas in a simplified theoretical reverberation chamber, based on the method of moments, and it uses the Ewald summation for efficient calculation of the cavity Green's function.
