Beamforming Capacity and SNR Maximization for Multiple Antenna Systems

  title={Beamforming Capacity and SNR Maximization for Multiple Antenna Systems},
  author={Syed Ali Jafar and A. Goldsmith}
We explore the optimal input distributions to maximize average received SNR and to achieve beamforming capacity on the downlink for two different channel models. First we model a scenario where the mobile unit is surrounded by local scatterers while the base station (BS) is relatively unobstructed, so that the channel matrix consists of i.i.d. rows and correlated columns. For this model we show that the average SNR maximizing input distribution also achieves the beamforming capacity. Then we… CONTINUE READING
