摘要: In this paper, we study carrier frequency offset estimation and correction for uplink multi-user MIMO (UL MU-MIMO) Wi-Fi, where distributed stations (STAs) send multiple data streams to a common access point (AP) with receive antennas. We provide description of the proposed system, propose three-step approach using joint phase algorithm synchronization that takes advantage existing pilot signals deliver good performance also has low complexity. simulation results demonstrate incurs negligible loss due offsets.
