LDPC Decoder Applications
DVB-S2X is the next generation satellite transmission standard which is an extended version of its well-established predecessor DVB-S2. The new specification allows for spectral efficiency gains of up to 50% by offering lower roll-off factors, higher modulations and a finer code rate granularity compared to DVB-S2.
