Abstract

A decoding iterative algorithm for second generation digital video broadcasting (DVB-S2) standard forward error correction (FEC) and variable coding and modulation (VCM) is proposed in this paper. This method makes full use of the link budget information provided by the VCM system. It predicts the number of decoding iterations for different modes, reduces the average number of iterations by 62%, and does not increase the checking cost. Then, using the FEC decoding structure of DVB-S2, the fast and reliable convergence of decoding is completed without increasing the complexity.
