Abstract: A modulation system for modulating a satellite uplink signal is described. The modulation system includes at least one computer device that includes an input interface, at least one software modulation engine, and at least one processing circuit. The input interface is configured to receive at least one input signal. The software modulation engine includes program code that is configured to modulate the at least one input signal when the software modulation engine is executed on the at least one processing circuit, thereby generating at least one IQ baseband data carrier (IQBBDC) signal based on the at least one input signal. Further, a modulation method for modulating a satellite uplink signal is described.

Abstract: The present invention discloses a processing device for processing a radio signal, comprising a plurality of receivers designed to receive the radio signal in a predetermined frequency range and to output each signal as a received signal, comprising a detection apparatus designed to detect, for each received signal, a number of sources in the corresponding radio signal, comprising a selection apparatus designed, if there is more than one source in at least one of the received signals, to select one of the receivers on the basis of the information on the number of sources in the individual received signals and to forward the received signal of said selected receiver. The present invention also discloses a corresponding method.
