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. WebE. Koyuncu, H.
