Relation between joint optimizations for multiuser MIMO uplink and downlink with imperfect CSI
Joint linear minimum sum mean-squared error (referred to as MSMSE) transmitter and receiver (transceiver) optimization problems are formulated for multiuser MIMO systems under a s...

Adaptive PSAM in SIMO systems with imperfect CSI in Rayleigh fading channels
In this paper we provide an adaptive modulation approach that uses adaptive pilot symbols which both pilot spacing and power allocation on pilot symbols are optimized in single in...

The Rate Loss of Single-Letter Characterization: The "Dirty" Multiple Access Channel
For general memoryless systems, the typical information theoretic solution - when exists - has a "single-letter" form. This reflects the fact that optimum performance ca...

Robust Beamforming for Security in MIMO Wiretap Channels with Imperfect CSI
—In this paper, we investigate methods for reducing the likelihood that a message transmitted between two multiantenna nodes is intercepted by an undetected eavesdropper. In part...
