Abstract: A distributed coordinated beamforming optimization scheme with the assistance of receive beamformer estimation was proposed for downlink cellular wireless communication systems. By sharing a small amount of information among cooperated base stations(BSs), the proposed algorithm estimates the receive vectors of related users at the BSs based on MVDR criterion, which are then utilized to optimize the design of transmit beamforming vectors. The simulation results and analysis show that the proposed distributed scheme can achieve the performance close to that in the centralized scheme with lower overhead and complexity. In addition, a simplified scheme was also proposed which further reduces the system over-head.
