On the ergodic sum-rate performance of CDD in multi-user systems
— The main focus of space-time coding design and analysis for MIMO systems has been so far focused on singleuser systems. For single-user systems, transmit diversity schemes suff...

Adaptive Precoding for Switching between Spatial Multiplexing and Diversity in MIMO OFDM with Transmit Antenna and Path Correlat
Abstract— The path and antenna correlations significantly degrade the system capacity in spatially-multiplexed multiple-input multiple-output (MIMO) orthogonal frequency-divisio...

On the Sum-Rate of Opportunistic Beamforming Schemes with Multiple Antennas at the Receiver
Abstract— The capacity region of Gaussian Multi-InputMultiple-Output (MIMO) broadcast channels has been shown to be achieved by dirty paper coding (DPC). However, due to the high...

On the design, selection algorithm and performance analysis of limited feedback transmit beamforming
Multiple-input multiple-output (MIMO) systems achieve significant diversity and array gains by using transmit beamforming. When complete channel state information (CSI) is not avai...
