Diversity Gain and MIMO Capacity for Nonisotropic Environments Using a Reverberation Chamber

Several physical parameters of realistic nonisotropic environments have been recently emulated with reverberation chambers. In this letter, the different performance in terms of diversity gain and multiple-input multiple-output (MIMO) capacity of the same linear MIMO array in different nonisotropic propagating scenarios is demonstrated with a reverberation chamber (RC) for the first time. This could be useful for designing antenna arrays in handset MIMO.
