An analytical approach for antenna performance evaluation for MIMO systems

An analytical approach for antenna performance evaluation in multiple-input-multiple-output (MIMO) systems is proposed. By considering the elevation angles of the electromagnetic rays at both the base station (BS) and mobile station (MS), a three-dimensional (3D) channel model is introduced. Then the analytical approach which evaluates the effects of antenna configurations on channel capacity and diversity performance of MIMO systems is derived. In order to verify the proposed method, a link-level simulation is implemented, in which the effects of isolation on system throughput, and the effects of envelope correlation coefficients (ECC) on equivalent diversity gain are evaluated, respectively. The simulation results validated our proposed approach.
