An Interdisciplinary Approach to Optimal Communication and Flight Operation of High-Altitude Long-Endurance Platforms

no code implementations1 Mar 2022 Sidrah Javed, Mohamed-Slim Alouini, Zhiguo Ding

We design optimal power allocation for downlink (DL) NOMA users along with the ideal position and speed of flight with the aim to maximize sum data rate during the day and minimize power expenditure during the night, while ensuring quality of service.

When Probabilistic Shaping Realizes Improper Signaling for Hardware Distortion Mitigation

no code implementations11 Sep 2020 Sidrah Javed, Ahmed Elzanaty, Osama Amin, Basem Shihada, Mohamed-Slim Alouini

We further present a hybrid shaping (HS) design to gain the combined benefits of both PS and geometric shaping (GS).

A Journey from Improper Gaussian Signaling to Asymmetric Signaling

no code implementations30 Apr 2020 Sidrah Javed, Osama Amin, Basem Shihada, Mohamed-Slim Alouini

The deviation of continuous and discrete complex random variables from the traditional proper and symmetric assumption to a generalized improper and asymmetric characterization (accounting correlation between a random entity and its complex conjugate), respectively, introduces new design freedom and various potential merits.
