A Converse Bound for Cache-Aided Interference Networks
Antonious M. Girgis, Ozgur Ercetin, Mohammed Nafie +1
In this paper, an interference network with arbitrary number of transmitters and receivers is studied, where each transmitter is equipped with a finite size cache. We obtain an inf…
Cache-Aided Heterogeneous Networks: Coverage and Delay Analysis
Mohamed A. Abd-Elmagid, Ozgur Ercetin, Tamer ElBatt
This paper characterizes the performance of a generic -tier cache-aided heterogeneous network (CHN), in which the base stations (BSs) across tiers differ in terms of their spati…
On Optimal Policies in Full-Duplex Wireless Powered Communication Networks
Mohamed A. Abd-Elmagid, Alessandro Biason, Tamer ElBatt +2
The optimal resource allocation scheme in a full-duplex Wireless Powered Communication Network (WPCN) composed of one Access Point (AP) and two wireless devices is analyzed and der…
Optimization of Energy-Constrained Wireless Powered Communication Networks with Heterogeneous Nodes
Mohamed A. Abd-Elmagid, Tamer ElBatt, Karim G. Seddik
In this paper, we study wireless networks where nodes have two energy sources, namely a battery and radio frequency (RF) energy harvesting circuitry. We formulate two optimization…
Pseudo-Lattice Treatment for Subspace Aligned Interference Signals
Yahya H. Ezzeldin, Karim G. Seddik
For multi-input multi-output (MIMO) K-user interference networks, we propose the use of a channel transformation technique for joint detection of the useful and interference signal…
Sparse Reconstruction-based Detection of Spatial Dimension Holes in Cognitive Radio Networks
Yahya H. Ezzeldin, Radwa A. Sultan, Karim G. Seddik
In this paper, we investigate a spectrum sensing algorithm for detecting spatial dimension holes in Multiple Inputs Multiple Outputs (MIMO) transmissions for OFDM systems using Com…
