Cooperative Beamforming and power allocation in 5G Cellular Networks

In this paper, a new algorithm is proposed for cooperative beamforming and power allocation in the downlink of multi-input multi-output (MIMO) 5G cellular networks. Increasing the data rate is the main goal of the 5G cellular networks. The proposed algorithm is developed based on a criterion in which the signal to interference plus noise ratio (SINR) of the one user is maximized subject to the other user s SINR and maximum allowable transmit power constraints. The transmitter and receiver beamforming vectors along with allocated powers to users are estimated by the proposed algorithm in an iterative manner. The performance of the proposed algorithm is evaluated by computer simulations and compared with the algorithms that are presented in [6]. The results show that our proposed algorithm outperforms the other methods.
