Optimal Beamforming for MIMO Shared Relaying in Downlink Cellular Networks with ARQ

Ahmed Raafat Hosny, Ramy Abdallah Tannious, Amr El-Keyi

In this paper, we study the performance of the downlink of a cellular network with automatic repeat-request (ARQ) and a half duplex decode-and-forward shared relay. In this system,…
