Abstract :
Multiple-input multiple-output wireless communication systems substantially suffer from RF Impairments in the course of the physical implementation of transceivers. In this paper, we study the performance of beamforming techniques in MU-MIMO (Multi-User MIMO) system with one transmitter and two receivers. We showed that the interference cancellation beamforming is suitable in the proposed scenario. In addition, we study the performance of MU-MIMO system with the suitable beamforming technique by taking RF impairments into account.
