Optimal multiuser transmit beamforming
WebThis paper considers a multi-cell multiuser spatial multiplex system with N cells and K users per cell with Nt antennas at each base-station and a single antenna at each remote user. Multiuser transmit beamforming is employed at each base-station. Let xi,j be a complex scalar denoting the information signal for the jth user in the ith cell, and ...

WebBeamforming for transmission in a network is, in several aspects, more difficult than beamforming for reception. At first sight, the problems appear to be equivalent; because the radio channel is reciprocal, a good uplink beamformer should also work well in the downlink. Another fundamental difference is the channel knowledge.
