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,…

Optimal Energy Allocation For Delay-Constrained Traffic Over Fading Multiple Access Channels
Antonious M. Girgis, Amr El-Keyi, Mohammed Nafie
In this paper, we consider a multiple-access fading channel where users transmit to a single base station (BS) within a limited number of time slots. We assume that each user h…
