Abstract
Disclosed are a distributed multi-cell multi-user beamforming method, a transmitter and a relevant system. In the distributed beamforming method in the embodiments of the present invention, beamforming coordinated calculation is performed by a plurality of transmitters, and an interference matrix among the transmitters is used to perform an iterative operation on a beamforming vector corresponding to the data which is to be sent to each user over each sub-channel of this cell, so that the interference dimension of each user over each sub-channel of the transmitters is compressed into a subspace as small as possible.
