Emulation of MIMO nonisotropic fading environments with reverberation chambers

摘要

Some recent publications have extended the emulatingcapabilities of reverberation chambers. While polarizationimbalance has been removed and Ricean-fading environmentsare now properly emulated, these chambers are still limited toisotropic nonline of sight (NLOS) scattering. By controlling thepower received, number of resolvable multipath components(MPC), angular spread (AS), and angle of arrival (AoA), the emulationof real-propagating environments with both isotropic andnonisotropic scattering are demonstrated in this letter using a reverberationchamber with several multiple-input–multiple-output(MIMO) arrays.
