User Effects on MIMO Performance: From an Antenna to a Link Perspective
The authors investigate in this paper the effects of the user's presence on the performance of a Multiple-Input Multiple-Output (MIMO) system in data and in voice usage scenarios. The investigation studies the user effects on the antenna performance and how these are incorporated into the MIMO channel and the link characteristics. The antennas and the user are deterministic. These are then integrated into the statistical 3GPP Spatial Channel Model (SCM) for a typical macrocell propagation environment setting. The channel performance is analyzed based on the average channel capacity, the average power transfer, the correlation, and the cumulative distribution function of the channel capacity as well as the link throughout and the error performance.
