Optimizing transmission rate in wireless channels using adaptive probes
Abstract— We consider a wireless system with multiple channels where each channel is either on or off, and probing the state of any channel incurs a cost. We present a polynomial...

Effect of Feedback Delay on Multi-Antenna Limited Feedback for Temporally-Correlated Channels
— A novel method based on Markov chain theory is proposed for analyzing the effect of feedback delay on a transmit beamforming system with limited feedback. Using this method, th...
