In this paper we present algorithms for transmitter adaptation in downlink wireless systems based on maximization of the Signal-to-Interference plus Noise-Ratio (SINR). We investigate their fixed-point properties in various scenarios and their relationship with optimal points in dual uplink scenarios.
