Abstract
Opportunistic beamforming was discussed using dumb antennas. The focus was on the downlink of a cellular system. Multiple antennas were used at the base-station to transmit the same signals from each antenna modulated by a gain whose phase and magnitude is changing in time in a controlled but pseudo random fashion. The scheme can be interpreted as performing opportunistic beamforming: the transmit powers and phases are randomized and transmission is scheduled to the user which is close to being in the beamforming configuration.
