Meta Distribution of Downlink Non-Orthogonal Multiple Access (NOMA) in Poisson Networks [PDF]
IEEE Wireless Communications Letters, 2018 We study the meta distribution (MD) of the coverage probability (CP) in downlink non-orthogonal-multiple-access (NOMA) networks. Two schemes are assessed based on the location of the NOMA users: 1) anywhere in the network and 2) cell-center users only ...

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 73-88, January/February 2026.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.

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 47-59, January/February 2026.The performance limitation in multiple‐input multiple‐output (MIMO) feeder links due to time and phase misalignment of the ground stations is investigated. Time and phase distribution over optical fiber is considered as an approach to achieve the synchronization requirements.
