DVB-S2X Wideband BCH and LDPC Decoder

 
The Creonic DVB-S2X wideband decoder is a silicon-proven, scalable solution that allows for symbol rates of up to 500 Msymb/s on state-of-the-art FPGAs.

 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.
