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…
Can Uplink Transmissions Survive in Full-duplex Cellular Environments?
Hesham ElSawy, Ahmad AlAmmouri, Osama Amin +1
In-band full-duplex (FD) communication is considered a potential candidate to be adopted by the fifth generation (5G) cellular networks. FD communication renders the entire spectru…
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…
