Belief propagation and variants are the usual decoding algorithms for low‐density parity check codes. The successive overrelaxations are applied to increase the convergence speed of the decoding process. Performances are reported and improvements over the reference algorithms are observed. This technique is also compatible with the high‐speed parallel group decoding involved in modern standards such as DVB‐S2.
