摘要：We investigate the uplink achievable rate and its approximation in the shared-antenna full-duplex massive MU-MIMO system. The proposed concise approximation depends on the channel distribution information rather than the instantaneous channel state information. We further analyze the spectral efficiency of this model based on the approximate results. In the discussion, we focus on the ZF and the MRT/MRC linear processing techniques which are commonly used in the massive MIMO systems. Monte-Carlo simulations show that our approximation is very close to the real result, and the shared-antenna full-duplex massive MU-MIMO system significantly outperforms the half-duplex system in terms of spectral efficiency when the scale of antenna array is large enough.
