The Creonic DVB-S2X demodulator is a low-complexity high-performance solution that allows for symbol rates of up to 100 MSymb/s on state-of-the-art FPGAs and performs all tasks of an inner receiver. The demodulator expects the quantized, complex baseband samples from an analog-digital-converter (ADC) and recovers timing, frequency and phase of the complex mapped symbols. In addition, the core handles PL frame recovery and PL de-framing. The demodulator’s output perfectly fits the Creonic DVB-S2X forward error correction IP core that implements LDPC and BCH decoding.
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.
