Joint Adaptive FDMA/SDMA in Chunk-Based OFDM Systems
—OFDM-FDMA/SDMA is currently considered as the leading transmission strategy for the downlink of beyond 3G mobile radio systems. When channel state information is available at th...

Joint channel estimation and resource allocation for MIMO systems-part I: single-user analysis
Multiple antenna systems are known to provide very large data rates, when the perfect channel state information (CSI) is available at the receiver. However, this requires the recei...

Minimum BER Transmit Beamforming for MIMO-OFDM Systems with Finite Rate Feedback
— In this paper, we consider minimum bit error rate (BER) beamforming (BF) for multiple–input multiple–output orthogonal frequency division multiplexing (MIMO–OFDM) systems...

Large system analysis of beamforming for MIMO systems with limited training
We consider multiple-input multiple-output (MIMO) systems exploiting the full diversity order of a MIMO fading channel via optimal beamforming and combining. Specifically, an analy...

The Impact of QoS Constraints on the Energy Efficiency of Fixed-Rate Wireless Transmissions
Transmission over wireless fading channels under quality of service (QoS) constraints is studied when only the receiver has channel side information. Being unaware of the channel c...
