Abstract: The fully digital multi‐carrier demodulator for the SpaceMux™ On‐Board Multimedia Processor implements a focussed subset of the DVB‐RCS transmission standard. This paper describes the design constraints and system considerations influencing the trades‐off, and the ensuing design. Aspects of the ASIC technology chosen for implementation are also addressed, as is the performance in the presence of signal imperfections.
