Embodiment Construction
[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0024] According to the distributed robust beamforming method of multi-cell coordination provided by the present invention, the multi-cell coordinated beamforming is a transmission mode of coordinated multi-point (CoMP) in a 4G wireless communication system. The method can suppress the co-channel interference between cells, guarantee the QoS of the cell edge users, and thus improve the overall throughput of the system.
