Power Allocation for Relayed OFDM with Index Modulation Assisted by Artificial Neural Network
Jiusi Zhou, Shuping Dang, Basem Shihada +1
In this letter, we propose a power allocation scheme for relayed orthogonal frequency division multiplexing with index modulation (OFDM-IM) systems. The proposed power allocation s…
When Probabilistic Shaping Realizes Improper Signaling for Hardware Distortion Mitigation
Sidrah Javed, Ahmed Elzanaty, Osama Amin +2
Hardware distortions (HWD) render drastic effects on the performance of communication systems. They are recently proven to bear asymmetric signatures; and hence can be efficiently…
Viral Aerosol Concentration Characterization and Detection in Bounded Environments
Osama Amin, Hayssam Dahrouj, Nojood Almayouf +3
Viral spread has been intermittently threatening human life over time. Characterizing the viral concentration and modelling the viral transmission are, therefore, considered major…
Relay Assisted OFDM with Subcarrier Number Modulation in Multi-Hop Cooperative Networks
Shuping Dang, Jiusi Zhou, Basem Shihada +1
Orthogonal frequency-division multiplexing (OFDM) with subcarrier number modulation (OFDM-SNM) manifests its superior nature of high spectral efficiency (SE) and low complexity for…
Energy-Efficient Fixed-Gain AF Relay Assisted OFDM with Index Modulation
Jiusi Zhou, Shuping Dang, Basem Shihada +1
To broaden the application scenario and reduce energy consumption, we propose an energy-efficient fixed-gain (FG) amplify-and-forward (AF) relay assisted orthogonal frequency-divis…
A Journey from Improper Gaussian Signaling to Asymmetric Signaling
Sidrah Javed, Osama Amin, Basem Shihada +1
The deviation of continuous and discrete complex random variables from the traditional proper and symmetric assumption to a generalized improper and asymmetric characterization (ac…
