An all-digital demodulation scheme for DVB-S2

摘要

In this paper, an all-digital demodulation scheme which is compliant with the second generation digital video broadcasting via satellites (DVB-S2) is presented. It works well for several modulation modes supported by DVB-S2 even under rather low signal-to-noise ratio (SNR). All algorithms adopted in this scheme have been described in detail and their computer simulation results have been shown. The symbol error rate (SER) performance from simulations is very close to the theoretical one.
