Abstract :
The second generation digital video broadcasting (DVB-S2) system has been standardized including the backward compatible (BC) mode with the operating standard DVB-S. BC mode has two conceptual ways implemented: hierarchical modulation and layered modulation. The paper describe the standardized BC modes and presents the simulation result to extract each DVB-S2 and DVB-S stream using the log likelihood ratio (LLR) algorithm
