Abstract: This letter presents a low-complexity redecoding-based error-floor lowering technique for quasi-cyclic low-density parity-check codes, where a predetermined set of variable nodes are attenuated before the redecoding. Using a two-stage off-line search, the attenuation set is… read more here.
