Due to lack of resources such as transmission power and bandwidth in satellite systems, resource allocation problem is a very important challenge. Nowadays, new heterogeneous network includes one or more satellites besides terrestrial infrastructure, so that it is considered that each satellite has multi-beam to increase capacity. This type of structure is suitable for a new generation of commu...
متن کاملUAS CNPC Satellite Link Performance – Sharing Spectrum with Terrestrial Systems
In order to provide for the safe integration of unmanned aircraft systems into the National Airspace System, the control and non-payload communications (CNPC) link connecting the ground-based pilot with the unmanned aircraft must be highly reliable. A specific requirement is that it must operate using aviation safety radiofrequency spectrum. The 2012 World Radiocommunication Conference (WRC-12)...

The design of effective traffic and resource management policies is a key issue in the deployment of ATM-satellite systems. This paper proposes a technique of call admission control and dynamic resource management to support ATM traffic classes in satellite environments. The effectiveness of the strategy is assessed by referring to the EuroSkyWay multimedia satellite platform, based on Ka-band ...
متن کاملExtending the Spectrum for Ka-band Satellite Systems by Use of the Shared Bands
The spectrum available in the exclusive Ka-bands has been shown to be insufficient to meet the demands of broadband access by satellite post 2020. This paper presents the work of the FP7 project CoRaSat in validating the use of the extra spectrum in the shared Ka bands for use by satellite. It is demonstrated that in the 17.3 to 17.7GHz band shared with Broadcasting Satellite Service (BSS) feed...
