Carrier Energy Dispersal for Systems Employing Angle Modulation by Analogue Signals or Digital Modulation in the Fixed-Satellite Service - Section 4C - Earth Station and Baseband Characteristics - Earth Station Antennas - Maintenance of Earth Stations
that use of carrier energy dispersal techniques in systems in the fixed-satellite service can result in a
substantial reduction of interference to stations of a terrestrial service operating in the same frequency bands
