Interference between Mobile and Satellite Communications

Interference Mitigation and Synchronization for Satellite Communications

Within this thesis, the satellite broadcast scenario of geostationary satellites is reviewed. The densely crowded geostationary arc in the common broadcast frequencies may create significant interference from adjacent satellites (ASI). The possible use of multiple-input receivers and of interference processing techniques is analyzed in this specific context. In addition the synchronization prob...

Robust Satellite Communications under Hostile Interference

Antenna System for Land Mobile Satellite Communications

Personal wireless communications is a true success story and has become part of people’s everyday lives around the world. Whereas in the early days of mobile communications Quality of Service (QoS) was often poor, nowadays it is assumed the service will be ubiquitous, of high speech quality and the ability to watch and share streaming video or even broadcast television programs for example is d...

Compressed Video Applications Through Mobile Satellite Communications

The National Aeronautics and Space Administration (NASA) has been involved in the development of an experimental K(20 GHz) and Ka-band (30 GHz) satellite known as the Advanced Communications Technology Satellite (ACTS). The Jet Propulsion Laboratory (JPL) has been commissioned to develop two different mobile satellite communication (satcom) terminals to operate with ACTS. The first terminal, wh...

Iterative interference cancellation for high spectral efficiency satellite communications

The problem of efficient utilization of the frequency spectrum for satellite systems is investigated; one which results as a consequence of highly crowding adjacent channels. An analytical characterization of the resulting interference channel is introduced and then exploited for interference cancellation. Two classes of cancelers are investigated. The first approach does not benefit from the f...
