Abstract:

Replica shuffled versions of iterative decodes for low-density parity-check (LDPC)codes and turbo codes are presented. The proposed schemes can converge faster than standard and plain shuffled approaches. Two methods, density evolution and extrinsic information transfer (EXIT) charts, are used to analyze the performance of the proposed algorithms. Both theoretical analysis and simulations show that the new schedules offer good tradeoffs with respect to performance, complexity, latency, and connectivity.
