Enhancing DVB-S2 Protocols: Cost-Effective Strategies and Performance Insights

This document outlines key considerations for enhancing the DVB-S2 protocols within the CCSDS framework. It discusses the purpose of these protocols, cost-reduction strategies for on-board and ground equipment, and terminology associated with DVB-S2, including MODCOD and dummy frames. Implementation issues are explored, including simplified processing of the baseband header and parallelization of LDPC encoding/decoding for high data rates. Performance analysis is provided with FER curves over various conditions, showing the effectiveness of DVB-S2 coding and modulation in real-world scenarios.
