Abstract :
This paper presents and discusses different approaches available to provide uplink protection to high data rate Users of an EHF satellite communication system, by combining temporal spreading gain with the spatial filtering of a spacecraft adaptive nulling antenna. The generalized performance of different nulling approaches is analyzed, as well as the limitations for simultaneously achieving high resolution over large field of view and wide bandwidth, when multiple Users access the satellite.
