SUMMARY This paper proposes a methodology for designing and optimizing the performance of adaptive coding and modulation (ACM) schemes for the forward link of unicast satellite broadband networks. The proposed technique of general applicability is based on the overall system capacity maximization conditioned on meeting a certain service area coverage for a(More)
— The exploitation of Adaptive Coding and Modulation (ACM) techniques for the forward link (satellite-to-user) of broadband communication satellites operating at Ka-band and above has been shown to theoretically provide large system capacity gains. In this article, the problem of how to accurately estimate the time variant channel and to adapt the physical(More)
SUMMARY This paper presents the detailed design and the key system performance results of a comprehensive laboratory demonstrator for a broadband Ka-band multi-beam satellite system exploiting the new DVB-S2 standard with adaptive coding and modulation (ACM). This complete demonstrator allows in-depth verification and optimization of the ACM techniques(More)
Due to their interactive nature, multimedia streams must be sent over UDP with suitable countermeasures for minimizing the effect of data loss. Coding with oversampled filter bank is a promising multiple description technique which allows for signal reconstruction even in presence of packet loss. Although the coded signal can be reconstructed by means of a(More)
