Asymmetric Degrees of Freedom of the Full-Duplex MIMO 3-Way Channel with Unicast and Broadcast Messages
Adel M. Elmahdy, Amr El-Keyi, Yahya Mohasseb +4
In this paper, we characterize the asymmetric total degrees of freedom (DoF) of a multiple-input multiple-output (MIMO) 3-way channel. Each node has a separate-antenna full-duplex…
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…
Proactive Location-Based Scheduling of Delay-Constrained Traffic Over Fading Channels
Antonious M. Girgis, Amr El-Keyi, Mohammed Nafie +1
In this paper, proactive resource allocation based on user location for point-to-point communication over fading channels is introduced, whereby the source must transmit a packet w…
On the Degrees of Freedom of SISO X-networks with Synergistic Alternating Channel State Information at transmitters
Ahmed Wagdy Shaban, Amr El-Keyi, Tamer Khattab +1
In this paper, we consider the two-user single-input single-output (SISO) X-channel and -user SISO X-network in fast fading environment. It is assumed that the transmitters have…
Achievable Degrees of Freedom of the K-user MISO Broadcast Channel with Alternating CSIT via Interference Creation-Resurrection
Mohamed Seif, Amr El-Keyi, Mohammed Nafie
Channel state information at the transmitter affects the degrees of freedom of the wireless networks. In this paper, we analyze the DoF for the K-user multiple-input single-output…
