abstract:
We focus on the globally optimal linear beamformer design based on quality-of-service (QoS) power minimization and balancing in the satellite downlink (DL) with perfect and statistical channel state information (CSI) users. Contrary to the usual rate requirements for the perfect CSI users, we consider ergodic rate requirements for the statistical CSI users. Assuming that the satellite works at Ka-band, we model the fading channels as zero-mean Gaussian vectors with rank-one covariance matrices....    »
