Abstract
A new early stopping criterion is proposed for the Noisy Gradient Descent Bit Flipping (NGDBF) Decoding of Low-Density Parity-Check (LDPC) codes to reduce the number of decoding iterations. The new criterion is based on the number of flipped bits at certain iterations, and has extremely low complexity. It is shown in the simulation results that the proposed early stopping criterion can significantly reduce the number of decoding iterations at low signal-to-noise ratios (SNRs), and only a slight bit error rate (BER) performance decrease is experienced at high SNRs.
