Comparative analysis of FEC subsystem in fixed satellite broadcasting standards

Satellite communication systems e.g. digital video broadcast satellite/terrestrial (DVB-S2/T2) have readily adopted LDPC code for Forward Error Correction (FEC), mostly due to its near Shannon performance at very low signal to noise. This paper summarizes the differences across FEC subsystems adopted in worldwide standards for next generation fixed satellite broadcasting. The goal of this analysis is to provide system designers an objective view of the different choices made in these standards and facilitate an easier system implementation for the same.
