Abstract
A `before convergence´ early stopping criterion (ESC) is proposed for the low-density parity check (LDPC) decoder defined in the second generation of digital video broadcasting (DVB) standards. The idea is to stop the decoding process once the estimated number of remaining errors is below the maximum capacity correction of the outer Bose-Chaudhuri-Hocquenghem (BCH) decoder used in the DVB-S2, -T2 and -C2 standards. Simulations show that the average number of iterations is reduced by up to 26% compared with the classical ESC.
