Experimental evaluation of MIMO terminals with user influence in OTA setups
Experimental evaluation of MIMO terminals with user influence in OTA setups
Abstract User influence, together with propagation environments and antenna designs, determines how well multiple-input–multiple-output (MIMO) terminals operate in true usage conditions. In this letter, we investigate to what extent the user influence affects the performance of a realistic MIMO terminal under various reproduced spatial channel models in a practical 3-D multi-probe anechoic chamber setup. A terminal mock-up, operating at 2.55 GHz, together with a realistic user phantom was used, and channel models with different spatial and polarization profiles, device under test with different operation modes and orientation angles were tested.
