DVB-RCS2 (Digital Video Broadcast – Second Generation DVB Interactive Satellite System) is the latest ETSI standard of the second generation for digital data transmission via satellites. It uses a new 16-state double-binary turbo decoder that significantly outperforms its dated 8-state counterpart of DVB-RCS. DVB-RCS2 is the first standard to adopt these highest performance turbo codes. New modulation schemes (8-PSK and 16-QAM) help to increase spectral efficiency even further. The outstanding error correction performance of the DVB-RCS2 turbo decoder makes it the ideal candidate for further applications where high spectral efficiency is key for lowering costs.
