Optimum Beamforming Using Transmit Antenna Arrays

  title={Optimum Beamforming Using Transmit Antenna Arrays},
  author={Visotsky and U. Madhow},
Transmit beamforming is a powerful means of increasing capacity in systems in which the transmitter is equipped with an antenna array, especially in systems in which receive beamforming is not available, as is typical in the base-to-mobile \downlink" in a cellular communication system. In this paper, the problem of transmit beamforming is formulated as one of minimizing the power radiated by the base station, subject to satisfying quality of service requirements at the mobiles.
