Abstract
In this paper, we study the impact of antennas and propagation channel on the block diagonalization (BD) capacity gain for 802.11ac Multi-User MIMO (MU-MIMO) in Home Networks. A correlated channel model is examined. The effect of the number of the transmit antennas, their spacing, and SNR is explored. It is shown that only a small increase of the number of transmit antennas over the total number of spatial streams increases the MU-MIMO capacity gain over SU-MIMO considerably. For example, a gain of 45% is achieved for a 20 dB SNR with 4 spatial streams and 6 transmit antennas. Additionally, the half wavelength antenna spacing is sufficient to take advantage of BD gain and to keep a transmit antenna with compact size. Based on simulations, we reveal the importance of a new channel correlation parameter to explain MU-MIMO capacity gain.
