Adjacent satellite interference from a network Of MF-TDMA satellite communications on-the-move terminals

Satellite Communications on-the-move (SOTM) networks are being deployed to provide various broadband communication services. Typically, an SOTM network consists of a large number of small aperture terminals deployed over a wide geographical area. These terminals are intended to operate over geostationary orbit satellites. To utilize network resources efficiently, these networks may employ time- and frequency-division multiple access methods. Also, SOTM terminals may operate using a range of antenna aperture sizes and may require different transmit power levels to meet various user´s data rate needs. Additionally, antenna pointing errors of the terminals may contribute to a time-varying interference pattern from the SOTM network to a victim receiver in another satellite network. This paper provides a methodology to analyze the time-varying interference resulting from an MF-TDMA network consisting of such terminals. This methodology has been submitted for consideration by ITU-R Working Party 4A.
