abstract:
We focus on a linear beamformer design in the downlink with statistical channel state information (CSI) at the transmitter, where the users’ ergodic rates are balanced. Simplifying the fading channels to given vectors with random scalar factors, which is a good approximation for rural mobile or satellite communications (SatCom), the stochastic model mismatch is kept small albeit the ergodic rate structure now allows for adapting the perfect CSI balancing algorithms. Although there is no equivale...    »
