DVB-RCS (Digital Video Broadcasting – Interaction channel for satellite distribution systems) is an established ETSIstandard for digital data transmission via satellites. It uses a 8-state double-binary turbo code that has an excellent error correction performance. This outstanding performance of the DVB-RCS turbo codes makes it the ideal candidate for further applications where high spectral efficiency is key for lowering costs.
