Rate analysis of distributed multiuser MIMO protocols for the 802.11 ac Conference Paper uri icon


  • Abstract: The 802.11 ac is a significant landmark in wireless communications, as it pushes towards new rate limits of more than one Gigabit per second, utilizing downlink multiuser multiple-input multiple-output (MIMO) beamforming to transmit data to various locations simultaneously. However, successful beamforming relies on intelligent user selection which requires extensive overhead of channel calibration between the AP and each of the candidate users, which hinders the utilization of multiuser MIMO. Thus, the subtle relation …
