Downlink transmitter adaptation based on greedy SINR maximization

On the uplink-downlink duality for Gaussian vector channels with colored noise and applications to CDMA transmitter adaptation

“…We note that while many algorithms are available for obtaining uplink CDMA codewords (see [10][11][12][13] and references therein) only a few algorithms have been proposed for downlink scenarios [14][15][16]. We also note that the uplink CDMA codeword ensembles can be designed to optimize various performance measures such as individual or sum rates and Signal-to-Interference+Noise-Ratios (SINR).…”
