Interference analysis in low earth orbit satellite systems

open access: yes, 2002
The LEO satellite systems will play an important role in the future personal communications networks because of their several advantages over GEO and MEO satellite systems. The extensive frequency reuse in a LEO Satellite System, in order to enhance the capacity, produces cochannel interference no matter what kind of multiple access scheme it is based ...
