Performance of Multibeam Satellite Systems with Tomlinson-Harashima Precoding

, 2009
A multibeam satellite system can be modelled as a multiple-input multiple-output (MIMO) system with an interbeam interference matrix that is derived from the positions of the users in the different beams.

The evaluation of Corona and Ikonos satellite imagery for archaeological applications in a semi-arid environment [PDF]

, 2004
Archaeologists have been aware of the potential of satellite imagery as a tool almost since the first Earth remote sensing satellite. Initially sensors such as Landsat had a ground resolution which was too coarse for thorough archaeological prospection ...

Satellite Internet

U ovom radu će se najprije razmotriti sami počeci satelitskih sustava koji su započeli svoj razvoj 1950-ih godina kada su počela prva eksperimentalna istraživanja i od tada je sama uporaba satelita značajno porasla.
