On the optimality of multiantenna broadcast scheduling using zero-forcing beamforming
Abstract--Although the capacity of multiple-input/multipleoutput (MIMO) broadcast channels (BCs) can be achieved by dirty paper coding (DPC), it is difficult to implement in practi...

A game-theoretic approach to energy-efficient power control in multicarrier CDMA systems
A game-theoretic model for studying power control in multicarrier code-division multiple-access systems is proposed. Power control is modeled as a noncooperative game in which each...
