Compared with the DVB-S standard, the DVB-S2 standard (The Second Generation Of Digital Video Broadcasting For Satellite Application) has greatly improved, the modulation is promoted to 16APSK, 32APSK from 8PSK, performance is greatly improved by adaptive coded modulation and the Error-correcting capability achieves about 3dB improvement. The reason why DVB-S2 has a better performance is

LDPC codes are the focal points in the research areas of channel coding. They have been attracting much attention in current and future digitial communication systems due to their Shannon limit-approaching performance and implementary potential of high speed encoding and decoding. Although some delightful achievements on theory and application research of LDPC codes have been
