Abstract

This paper deals with the design, evaluation and performance comparison of smart framing strategies that complement the packet scheduler in DVB-S2 systems with adaptive coding and modulation. Provided that user data packets are transmitted grouped in frames, each of them using a modulation and coding setting (ModCod), the inherent spectral efficiency of the selected ModCod can be cancelled by a poor framing efficiency, i.e. transmitting frames with large padding component. For this reason, smart framing strategies are proposed in this paper, which optimize the framing efficiency.
