Abstract
Embodiments disclosed herein relate generally to digital transponders. In one broad aspect, there is provided a digital transponder comprising: (a) an analog to digital converter configured to receive a real analog wideband multi-carrier signal and generate a real digital wideband multi-carrier signal from the real analog wideband multi-carrier signal, the real analog wideband multi-carrier signal spans M element channels, M being an integer greater than or equal to one; (b) a channelizer configured to channelize the real digital wideband multi-carrier signal intoM channelized digital signals, theM channelized digital signals comprising M pairs of channelized digital signals, each pair of channelized digital signals comprising a primary channelized digital signal and a secondary channelized digital signal, the secondary channelized digital signal being an image of the primary channelized digital signal; (c) a switch matrix and signal construction module configured to generate a plurality of intermediate signals from only the primary channelized digital signals, the plurality of intermediate signals comprising pairs of intermediate signals, each pair comprising a primary intermediate signal and a secondary intermediate signal, the secondary intermediate signal being an image of the primary intermediate signal; (d) at least one synthesizer, the at least one synthesizer configured to combine at least one pair of intermediate signals to generate a real digital output signal; and (e) at least one digital to analog converter, the at least one digital to analog converter configured to convert the real digital output signal to an analog output signal.
