Exploiting Spatial Channel Covariance for Hybrid Precoding in Massive MIMO Systems Abstract: We propose a new hybrid precoding technique for massive multi-input multi-output (MIMO) systems using spatial channel covariance matrices in the analog precoder design. Applying a regularized zero-forcing precoder for the baseband precoding matrix, we find an unconstrained analog precoder that maximizes signal-to-leakage-plus-noise ratio […]

Comments Off on Differential Feedback of Geometrical Mean Decomposition Precoder for Time-Correlated MIMO Systems
Posted in: IEEE 2017, MATLAB
Differential Feedback of Geometrical Mean Decomposition Precoder for Time-Correlated MIMO Systems Abstract: For a time-correlated channel, we consider the differential feedback of the geometrical mean decomposition (GMD) precoder, which is known to be optimal for a number of criteria. When the channel varies slowly, we can expect the optimal GMD precoders of consecutive channel uses […]
