Effective Capacity Maximization in Multi-Antenna Channels with Covariance Feedback
Abstract—The optimal transmit strategies of single-user multiantenna systems with respect to average capacity maximization are well understood. However, the performance measure d...

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...

On the capacity achieving covariance matrix for Rician MIMO channels: an asymptotic approach
In this contribution, the capacity-achieving input covariance matrices for coherent blockfading correlated MIMO Rician channels are determined. In contrast with the Rayleigh and u...
