| Abstract | In this letter, we address the issue of early stopping criterion for layered LDPC decoders, aiming at more safeness with low hardware cost and minimum latency. We introduce a new on-the-fly measure in the decoder, called in-between layers partial syndrome, and define a family of stopping criteria, with different tradeoffs among complexity, latency, and performance. Numerical results show that our stopping criteria surpass existing solutions, and can be as safe as the full-syndrome detection, down to frame error rates (FERs) as low as FER = 10-8. © 2017 IEEE. |
