Incoherent Digital Holography Empowered by Wavefront and Information Engineering: A Review

open access: yesAdvanced Photonics Research, EarlyView.
Advancements in incoherent digital holography (IDH) have been achieved via wavefront engineering (using spatial light modulators, diffractive optics, and metasurfaces) and information engineering (using compressive sensing and deep learning). This paper presents an overview of IDH with wavefront and information engineering, paving the way toward its ...

Contribution of non‐orthogonal multiple access signalling to practical multibeam satellite deployments

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView., 2023
The potential gains of NOMA were evaluated in a satellite system with heterogeneous receivers, after considering the use of specific DVB‐S2X MODCODs, along with the impact of non‐linearities. It was concluded that a judicious power allocation in NOMA, jointly optimized with the IBO of the PAs, can yield significant sum‐rate gains.
