http://tailieudientu.lrc.tnu.edu.vn/Upload/Collection/brief/brief_42073_45917_6620148523711.pdf WebThe LP DVB-S2-compliant signal is BCH and LDPC encoded, with LDPC code rates 1/4, 1/3, 1/2 or 3/5. Then the hierarchical mapper generates the non-uniform 8PSK constella-tion: the two HP DVB-S bits define a QPSK constellation point, while the single bit from the DVB-S2 LDPC encoder sets an additional rotation ±θ before transmission.
