Abstract [en]

In wireless systems with multiple antennas at the access points, the downlink power has to be spatially optimized to allow several simultaneous users. We consider two different MMSE criteria for a multi-user downlink CDMA system and determine the optimal transmit beamforming weights. The MMSE criteria with and without receiver gain control are compared for a system where the transmitter is equipped with an antenna array and the receivers have single antennas. The MMSE and SINR versus different number of users is shown and the effect of including the gain control in the MMSE criteria is clearly demonstrated.
