Overview and general principles of source coding, channel coding & modulation in CCSDS and DVB-S standards

Two standardization bodies are currently actively working in the field of space links communication protocols: CCSDS and DVB. These two bodies have developed and specified a series of channel coding and modulation techniques which specifically address the specificities and constraints of space links. Nevertheless, CCSDS and DVB standards differ in many instances because they try to answer different system requirements. The aim of this paper is to present an overview of those techniques with performance comparison between CCSDS and DVB as far as channel coding and modulation are concerned.
