Abstract:

Replica shuffled versions of iterative decoders of low-density parity-check codes and turbo codes are presented in this paper. The proposed schemes can converge faster than standard and plain shuffled approaches. Two methods, density evolution and EXIT charts, are used to analyze the performance of the proposed algorithms. Both theoretical analysis and simulations show that the new schedules offer good trade-offs with respect to performance, complexity, latency and connectivity.
