DVB-RCS2 Modulator

The DVB-RCS2 modulator is a low-complexity high-performance solution that allows for symbol rates of up to 160 MSymb/s on state-of-the-art FPGAs. The IP core performs all tasks of the inner transmitter and complements the Creonic DVB-RCS2 receiver solutions (DVB-RCS2 demapper and DVB-RCS2 turbo decoder).

DVB-RCS2 is the first standard to adopt the high performance 16-states 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 code makes it the ideal candidate for further applications where high spectral efficiency is key for lowering costs.
