摘要： An apparatus for a satellite communication system is provided, the apparatus comprises: means for monitoring a plurality of frequency channels demultiplexed from a signal comprising one or more carriers; means for identifying at least one frequency channel of the plurality of frequency channels comprising interference; and means for removing the identified at least one frequency channel before the one or more carriers are reformed. By removing the frequency channels comprising interference, the signal-to-noise ratio of a carrier can be improved. Also, if the interference occurs within a carrier, the carrier is usable as long as the removed frequency channels are considerably narrower than the carrier.
