Title:
Bilinear Precoding for FDD Massive MIMO System with Imperfect Covariance Matrices 
Abstract:
This work deals with a massive multiple-input-multiple-output (MIMO) system operating in frequency division duplex (FDD) mode. We propose a linear precoding technique for the downlink (DL) transmission, where we exploit the second-order information of the DL channel gained from an extrapolation of the uplink (UL) channel covariance. Contrary to the instantaneous channel state information (CSI), which is not reciprocal, the channel covariance matrix depends on the so-called angular scattering fun...    »
