Optimal Downlink Beamforming Using Semidefinite Optimization

  title={Optimal Downlink Beamforming Using Semidefinite Optimization},
  author={Mats Bengtsson and Bj{\"o}rn Ottersten},
When using antenna arrays at the base station of a cellular sy stem, one critical aspect is the transmission strategy. An optimal choice of beamform ers for simultaneous transmission to several co-channel users must be solved jointly for a ll users and base stations in an area. We formulate an optimal transmit strategy and show how t e solution can be calculated efficiently using interior point methods for semidefin ite optimization. The algorithm minimizes the total transmitted power under… CONTINUE READING
