The choose to perform a C-OFDM modulation directly by satellite makes the design of cost-effective new communication scenarios possible, in periods in which satellite communications call for a higher penetration in everyday services provision, avoiding the high costs of terrestrial - segment infrastructures to make the satellite signal exploitable by mobile users in urban environments. This paper focuses on the analysis of the performances of a C-OFDM-based communication scheme for the provision of a high quality and scalable bit rate radio signal over satellite links and exploitable in urban environments. Due to these preambles, the almost unemployed specifically satellite-oriented Mode-III of the DAB standard is considered, in conjunction with the design of an high-effective receiver based on soft-decision schemes, in cohabitation with almost very spread terrestrial DAB services. The degradations due to propagation and signal distortions introduced by the payload are also taken into account in the analysis of the transmission system.
