Characterization of Reverberation Chambers for OTA Measurements of Wireless Devices: Physical Formulations of Channel Matrix and New Uncertainty Formula [PDF]
IEEE Transactions on Antennas and Propagation, 2012 The paper deals with reverberation chambers for over-the-air (OTA) testing of wireless devices for use in multipath. We present a formulation of the S-parameters of a reverberation chamber in terms of the free space S-parameters of the antennas, and the ...

Reverberating chamber profile identification
IET Microwaves, Antennas & Propagation, 2012 This study proposes a model, based on the generalised K (GK) distribution, for identifying the reverberating chamber (RC) propagation channel profiles. Following this rationale, a parameter, given by a proper combination of GK parameters, is not only able to clearly distinguish between line-of-sight (LOS) and non-line-of-sight conditions, but it is ...

Spatial Resolution of Late Reverberation in Virtual Acoustic Environments
Trends in Hearing, 2021 Late reverberation involves the superposition of many sound reflections, approaching the properties of a diffuse sound field. Since the spatially resolved perception of individual late reflections is impossible, simplifications can potentially be made ...

Characterization of Reverberation Chamber - A Comprehensive Review
IEEE Access, 2020 This study presents a comprehensive review of the characterization techniques of a reverberation chamber (RC). After describing the limitations of the theoretical models for the determination of the lowest usable frequency (LUF) of a chamber, the ...

Predicting theater chair absorption from reverberation chamber measurements - comment [PDF]
, 1993 The relationship between the measured acoustic absorption coefficient of an array of theater chairs and the ratio of the perimeter length to plan area of the array is considered.

FDTD modelling of reverberation chamber
Electronics Letters, 2005 The finite-difference time-domain (FDTD) method is applied to the simulation of a reverberation chamber. The real losses of the reverberation chamber are taken into account in a post-treatment process. The predicted results are compared with measured data and good agreement is reported.

Spatial Correlation and Ergodic Capacity of MIMO Channel in Reverberation Chamber
International Journal of Antennas and Propagation, 2012 It has previously been shown that a reverberation chamber can conveniently be used to measure ergodic multiple-input multiple-output (MIMO) capacity for over-the-air (OTA) tests.

Measurement of Absorption Cross Section of a Lossy Object in Reverberation Chamber Without the Need for Calibration [PDF]
, 2016 A reliable and simple procedure is proposed to measure the averaged absorption cross section (ACS) of a lossy object in a reverberation chamber (RC). This procedure is based on the time-domain measurement of the ACS in an RC.

The Effect of Zigzag Boundaries on the Reverberation Chamber Performance
IEEE Access, 2021 The stirrer design is important in a reverberation chamber measurement system. Previous study shows that the rotating radius of the stirrer plays a key role for the stirrer performance. However, to identify the contribution from the structure, optimizing
