Grassmannian predictive coding for limited feedback multiuser MIMO systems
Grassmannian beamforming is an efficient way to quantize channel state information in multiple-input multiple-output wireless systems. Unfortunately, multiuser systems require la...

Analog beamforming in MIMO communications with phase shift networks and online channel estimation
In multiple-input multiple-output (MIMO) systems, the use of many radio frequency (RF) and analog-to-digital converter (ADC) chains at the receiver is costly. Analog beamformers op...

Amplify-and-Forward Capacity with Transmit Beamforming for MIMO Multiple-Relay Channels
In this paper, we consider a MIMO wireless relay network where communication between a source and a destination node is assisted by multiple relay nodes using the Amplifyand-Forwar...
