DVB-S2X is a digital satellite television broadcast standard. It has been standardised by DVB Project in March 2014 as an optional extension of DVB-S2 standard.[1] It will also become an ETSI standard.[2]
Compared to DVB-S2, efficiency gains up to 51% can be achieved with DVB-S2X.[3]
Amongst improvements are:
Higher Modulation Schemes (64/128/256APSK)
Smaller Roll-off factors
Improved filtering making it possible to have smaller carrier spacing
