Abstract
A system and method for providing at least one transmit precoder includes transforming at least one of a weighted sum-rate and max-min rate objective into two or more sub-problems by introducing at least one slack variable. The two or more sub-problems are iterated on a computer readable storage medium to provide at least one transmit precoder for each transmitter.

A method for providing at least one transmit precoder, comprising:
- transforming at least one of a weighted sum-rate and max-min rate objective into two or more sub-problems by introducing at least one slack variable;
- and
- iterating the two or more sub-problems on a computer readable storage medium to provide at least one transmit precoder for each transmitter.
A method for providing at least one transmit precoder, comprising:
- transforming at least one of a weighted sum-rate and max-min rate objective into two or more sub-problems by introducing at least one slack variable, wherein the at least one objective has imperfect channel state information, and further wherein the two or more sub-problems are formulated as at least one of a convex optimization problem and a problem explicitly solvable in closed form;
- applying the Schur complement to convert infinitely many inequalities into a finite number of linear matrix inequalities;
- iterating the two or more sub-problems on a computer readable storage medium to provide at least one transmit precoder for each transmitter.
A system for providing at least one transmit precoder, comprising:
- a transformation module configured to transform at least one of a weighted sum-rate and a max-min rate objective into two or more sub-problems by introducing at least one slack variable;
- and
- a solving module configured to iterate the two or more sub-problems on a computer readable storage medium to provide at least one transmit precoder for each transmitter.
