Usage Analysis in a MIMO Channel for Voice and Data

We investigate the effects of the user presence on a multi-antenna design from the channel perspective. Two usage scenarios are investigated, data and voice. The antennas and the user are electromagnetically simulated and are then integrated into the statistical 3GPP spatial channel model. There, the channel statistics are analyzed through the average channel capacity, correlation, and the channel power transfer. It was found that the presence of the user contributed to a loss up to 50% in the channel power. The data position was found to be the lowest in terms of channel capacity. The user orientation caused the most variability in the performance for the voice position, while it had negligible impact on performance in the data position.
