Arbitrary fading emulation using mode-stirred reverberation chambers with stochastic sample handling

Mode stirred reverberation chambers (MSC) are used for measuring different antenna parameters, including some related to MIMO. In a single-cavity MSC, conventionally known as reverberation chamber, the environment is isotropic and the amplitude of the signal is Rayleigh distributed. This contribution presents novel methods to accurately emulate a more realistic distribution from a Rayleigh-fading distribution by selecting parts of the sample set that forms different statistical ensembles. The results will also show the potential of using the algorithms as a real-time fading emulation for antenna testing.
