摘要: The proof-of-concept research on orthogonal frequency division multiplexing uplink multi-user multiple-input multiple-output (OFDM UL MU-MIMO) technology has been complemented by the industry and academia with additional activities consequences of non-ideal impairments in system performance. In this paper, we analyze design algorithms to mitigate joint effects carrier offset, in-phase quadrature imbalance, differences receive power time-of-arrival performance OFDM MU-MIMO, one main novel technologies physical layer portfolio sixth-generation wireless local area networks under developing IEEE Task Group 802.11ax.
