The CCR considering a) that one of the principal limitations in achieving greater utilization of the RF spectrum and geostationary orbit for the fixed-satellite service (FSS) is mutual interference among satellite networks operating in common frequency bands and serving the same or adjacent geographical areas; b) that inter-satellite network interference protection is primarily achieved by earth-station antenna discrimination; c) that other techniques such as frequency re-use, improved modulation, higher power satellite transmitters and lower noise receivers may be used to increase communication capacity; d) that some of these techniques increase the susceptibility of sateliite networks to mutual interference; e) that the deleterious effects of some of these techniques may be reduced through the employment of interference canceiling devices; f) that the basic principle of interference cancellers is to construct a replica of an interfering signal in both amplitude and phase, and to phase invert the replica and add it to the wanted signal plus interference.
