Abstract
In adaptive transmitter diversity, the complex weights applied to the downlink antennas are obtained from the instantaneous complex gains in the uplink. This paper provides the first analysis of the effects of decorrelation of gains between the uplink and downlink and of number of antennas, and the first assessment of the effect of fading when the method supports multiple users
