Abstract: Replica shuffled versions of iterative decoders of turbo codes, low-density parity-check codes and turbo product codes are presented. The proposed schemes converge faster than standard and previously proposed "shuffled" approaches. Simulations show that the new schedules offer good performance versus complexity/latency trade-offs.
