Power Minimization with Rate Constraint in Downlink Multi-Cell Cooperative MIMO Systems |
Abstract | ||
|---|---|---|
Green radio has attracted much attention currently, and among the many factors to be considered, power consumption reduction is of great significance. In this paper, we consider a power minimization problem with rate requirement and power constraints for downlink multi-cell cooperative MIMO(Co-MIMO) systems. A transmit signal covariance design scheme is proposed, and an integrated algorithm is developed to search the optimal covariance for power minimization. Numericalsimulations verify the optimality of our proposed transmit signal covariance scheme. A significant performance gain is observed over the uniform power allocation (UPA) and the noncooperative geometric mean decomposition (GMD)-based schemes. |
