On the Decision Boundaries of Neural Networks: A Tropical Geometry Perspective
Motasem Alfarra, Adel Bibi, Hasan Hammoud +2
This work tackles the problem of characterizing and understanding the decision boundaries of neural networks with piecewise linear non-linearity activations. We use tropical geomet…
Full-Duplex Relaying with Improper Gaussian Signaling over Nakagami-m Fading Channels
Mohamed Gaafar, Mohammad Galal Khafagy, Osama Amin +2
We study the potential employment of improper Gaussian signaling (IGS) in full-duplex relaying (FDR) with non-negligible residual self-interference (RSI) under Nakagami- m fading.…
Improper Signaling for Virtual Full-Duplex Relay Systems
Mohamed Gaafar, Osama Amin, Rafael F. Schaefer +1
Virtual full-duplex (VFD) is a powerful solution to compensate the rate loss of half-duplex relaying without the need to full-duplex capable nodes. Inter-relay interference (IRI) c…
Improper Signaling in Two-Path Relay Channels
Mohamed Gaafar, Osama Amin, Rafael F. Schaefer +1
Inter-relay interference (IRI) challenges the operation of two-path relaying systems. Furthermore, the unavailability of the channel state information (CSI) at the source and the l…
Petroleum Refinery Multi-Antenna Propagation Measurements
Mohamed Gaafar, Geoffrey G Messier
This paper presents the results of the first multi- antenna propagation measurement campaign to be conducted at an operating petroleum refining facility. The measurement equipment…
Improper Gaussian Signaling in Full-Duplex Relay Channels with Residual Self-Interference
Mohamed Gaafar, Mohammad Galal Khafagy, Osama Amin +1
We study the potential employment of improper Gaussian signaling (IGS) in full-duplex cooperative settings with residual self-interference (RSI). IGS is recently shown to outperfor…
Underlay Spectrum Sharing Techniques with In-band Full-Duplex Systems using Improper Gaussian Signaling
Mohamed Gaafar, Osama Amin, Walid Abediseid +1
Sharing the spectrum with in-band full-duplex (FD) primary users (PU) is a challenging and interesting problem in the underlay cognitive radio (CR) systems. The self-interference i…
Sharing the Licensed Spectrum of Full-Duplex Systems using Improper Gaussian Signaling
Mohamed Gaafar, Osama Amin, Walid Abediseid +1
Sharing the spectrum with in-band full-duplex (FD) primary users (PU) is a challenging and interesting problem in the underlay cognitive radio (CR) systems. The self-interference i…
Spectrum Sharing Opportunities of Full-Duplex Systems using Improper Gaussian Signaling
Mohamed Gaafar, Osama Amin, Walid Abediseid +1
Sharing the licensed spectrum of full-duplex (FD) primary users (PU) brings strict limitations on the underlay cognitive radio operation. Particularly, the self interference may ov…
