Web16-APSK DVB-S2 32-APSK The performance of the AR4JA LDPC codes on a binary-input additive white Gaussian noise (AWGN) channel is well-documented [1,2]. Such published performance results apply to binary phase-shift keying (BPSK) or quadrature PSK (QPSK) modulation, as is typically used in deep space missions. WebDVB-S2 is intended to provide Direct-To-Home (DTH) services for consumer Integrated Receiver Decoder (IRD), as well as collective antenna systems (Satellite Master Antenna Television - SMATV) and cable television head-end stations (possibly with remodulation, see EN 300 429 [5]).
