DIGITAL RESOURCE PROTECTION METHOD AND RELATED DEVICE

摘要

Disclosed are a distributed multi-cell multi-user beamforming method, a transmitter, and a related system. In the distributed beamforming method in the embodiments of the present invention, beamforming coordinated computation 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 data which is to be sent to each user over each sub-channel of a 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, and dimensions are obtained as many as possible to transmit useful data. The technical solution provided by the present invention can effectively increase the cell channel capacity and the throughput of the whole system.
