On the impact of residual CFO in UL MU-MIMO
ICASSP 2016accepted
Uplink multiuser MIMO (UL MU-MIMO) is a new feature introduced in 802.11ax (currently under development). This paper investigates the residual carrier frequency offset (CFO) impact on the performance of UL MU-MIMO OFDM systems. We show that if a station (STA) has zero residual CFO, then its packet e…
