MIMO (Multiple-Input and Multiple-Output) wireless communications can increase throughput in cellular systems by using multiple antennas in order to simultaneously transmit multiple users' data. Beamforming is a signal processing technique that enables antenna arrays to create directional signals, increasing transmitter or receiver gain. The authors propose a new adaptive user antenna beamforming technique for multi-cell cooperative networks which simultaneously communicates with multiple available BSs and RSs using the MS's multiple antennas. They show that the proposed adaptive beamforming technique outperforms distributed beamforming by increasing the data rate with less degradation of the BER.
