Small satellites and CubeSats: Survey of structures, architectures, and protocols
Franco Davoli,Charilaos I. Kourogiorgas,Mario Marchese,Athanasios D. Panagopoulos,Fabio Patrone +4 more
TL;DR: The space environment is still challenging but is becoming more and more attractive for an increasing number of entities and one widely used type of small satellite is the CubeSat, whose different aspects are surveyed in the following: mission goals, hardware subsystems and components, possible network topologies, channel models, and suitable communication protocols.
Journal ArticleDOI
Precoding, Scheduling, and Link Adaptation in Mobile Interactive Multibeam Satellite Systems
Miguel Angel Vazquez,M. R. Bhavani Shankar,Charilaos I. Kourogiorgas,Pantelis-Daniel Arapoglou,Vincenzo Icolari,Symeon Chatzinotas,Athanasios D. Panagopoulos,Ana I. Perez-Neira +7 more
TL;DR: Under realistic conditions, the numerical results show that precoding can offer an attractive gain in the system throughput compared with the conservative frequency reuse allocations.
Journal ArticleDOI
Cooperative Hybrid Land Mobile Satellite---Terrestrial Broadcasting Systems: Outage Probability Evaluation and Accurate Simulation
TL;DR: The outage performance of a cooperative hybrid satellite and terrestrial system configuration is analytically evaluated assuming that the satellite links suffer from shadowed Rician fading, while the terrestrial link suffers from the Nakagami-m fading.
Journal ArticleDOI
Cloud Attenuation Statistics Prediction From Ka -Band to Optical Frequencies: Integrated Liquid Water Content Field Synthesizer
TL;DR: A unified space-time model for the prediction of induced attenuation due to clouds for frequencies above Ka-band up to optical range is presented and shows encouraging results.
Journal ArticleDOI
On the Earth-Space Site Diversity Modeling: A Novel Physical-Mathematical Outage Prediction Model
TL;DR: In this paper, a novel model based on the bivariate inverse Gaussian (IG) distribution is presented for the prediction of the outage performance of a dual site diversity Earth-space system.
