Distributed Multibase Collaborative Transmission for MIMO OFDM with Zero Forcing Beamforming

This paper addresses the problem cooperative downlink transmission in multicell multiantenna cellular networks. We have presented scheme for base station coordination and cooperation in MIMO with zero forcing beamformig system. Firstly, a projected channel matrices is given and it make the beams steer into the preferred user direction. Secondly, partial collaboration transmission and distributed scheduling method have been proposed. These approaches can reduce the complexity of user selection and achieve reasonable performance.
