Multiuser MIMO Downlink Transmission Over Time-Varying Channels
—— The performance of multiuser MIMO downlink systems with block diagonalization (BD) relies on the channel state information (CSI) at the transmitter to a great extent. For ti...

Downlink Limited Feedback Transmission Schemes for Asymmetric MIMO Channels
Abstract—In multiple-input multiple-output (MIMO) broadcast channels, multiuser diversity is exploited by scheduling data transmission to users with best channel conditions. To ...

Generalization of Channel Inversion Algorithms for Multiuser MIMO Downlink Systems
— Recently a number of transmission schemes have been introduced to achieve sum capacity for multiuser multiinput multi-output (MIMO) broadcast channels (BC). A block diagonaliza...

A Decomposition-Based Low-Complexity Scheduling Scheme for Power Minimization under Delay Constraints in Time-Varying Uplink Cha
Abstract— In this paper, we investigate the problem of minimizing the average transmission power of users while guaranteeing the average delay constraints in time-varying uplink ...

A New SLNR-based Linear Precoding for Downlink Multi-User Multi-Stream MIMO Systems
—Signal-to-leakage-and-noise ratio (SLNR) is a promising criterion for linear precoder design in multi-user (MU) multiple-input multiple-output (MIMO) systems. It decouples the p...
