Impact of EIRP Constraint on MU-MIMO 802.11ac Capacity Gain in Home Networks
Résumé
In this paper, we evaluate a downlink MultiUser Multiple-Input Multiple-Output (MU-MIMO) scenario, in which a 802.11ac access point with multiple antennas (up to 10) is transmitting to two receivers, each one with two antennas. Block diagonalization (BD) method is investigated under the Equivalent Isotropic Radiated Power (EIRP) constraint. This study shows that scaling the transmitted power according to the EIRP constraint can improve the multiuser (MU) sum capacity to single-user (SU) capacity ratio compared to the gain achieved under the transmitted power constraint.
