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.

摘要： The invention relates to the implementation of a digital signal processor that is required to process a large number of narrowband analogue input or output signals. Analogue processing is performed to combine multiple analogue signals together (with non-overlapping frequency bands) into a composite signal which is fed to a single analogue to digital converter. These signals come from different sources and would in a conventional implementation use individual converters. Analogue signal processing is used outside of the digital signal processor and digital processing is used inside to enable the original analogue signals to be reconstructed in the digital domain in the same format as if individual converters have been used. A similar technique can be applied to digital to analogue conversion interfaceswhere a digital combining operation is performed to combine digital sub-band signals into a single composite signal, prior to input to a single digital-to-analogue(DAC) converter for conversion to the analogue domain and subsequently to an analogue splitter device for separation into a plurality of analogue signals.Hence, the technique can be implemented in both transmitter and receiver systems.
