A Hybrid NOMA-OMA Scheme for Inter-plane Intersatellite Communications in Massive LEO Constellations
Donatella Darsena, Giacinto Gelli, Ivan Iudice +1
Communication between satellites in low-Earth orbit (LEO) constellations takes place through inter-satellite links (ISLs). Unlike intra-plane ISLs, which interconnect satellites be…
On the Capacity of Opportunistic Time-Sharing Downlink with a Reconfigurable Intelligent Surface
Donatella Darsena, Francesco Verde
We provide accurate approximations of the sum-rate capacity of an opportunistic time-sharing downlink, when a reconfigurable intelligent surface (RIS) assists the transmission from…
Rapidly time-varying reconfigurable intelligent surfaces for downlink multiuser transmissions
Francesco Verde, Donatella Darsena, Vincenzo Galdi
Until now, researchers in wireless communications have mainly focused their attention on slowly time-varying designs of reconfigurable intelligent surfaces (RISs), where the spatia…
