• Layered LDPC decoder
• early termination
• in-between layers partial syndrome

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).
