Abstract
Embodiments include methods and devices for processing a digital composite signal generated at a first sampling rate. The signal includes at least first and second carrier-bands arranged to define a first inner gap between the carrier-bands. The first inner gap includes at least a first gap between the highest frequency of the first carrier-band and the lowest frequency of the second carrier-band. The digital composite signal has a predetermined instantaneous bandwidth that is lower than a sampling bandwidth. An outer gap located outside the instantaneous bandwidth and within the sampling bandwidth is determined. The first inner gap is reduced to define a second inner gap, where a width of the second inner gap is related to a width of the outer gap. The resulting folded digital composite signal is decimated to a second sampling rate lower than the first sampling rate thereby creating a decimated folded digital composite signal.
