Adaptive Beamforming with Per-Antenna Feedback for Multi-Cell Cooperative Networks

Beamforming is a signal processing technique that enables antenna arrays to create directional signals, increasing transmitter or receiver gain. We 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. We show that the proposed adaptive beamforming technique outperforms distributed beamforming by increasing the data rate with less degradation of the BER.This work was supported by Basic Science Research Programs through the National Research Foundation by Korea (NRF) funded by the Ministry of Education, Science and Technology (2012-0002490)
