In this letter, we address the problem of early stopping of iterative decoding of LDPC codes, driven by criteria ensuring that no errors occur from premature termination. A safe termination strategy developed for Turbo codes is generalized to layered LDPC decoding. Then, a more efficient version and also two less efficient, but less complex, criteria are proposed.

Abstract
In this letter, we address the problem of early stopping of iterative decoding of LDPC codes, driven by criteria ensuring that no errors occur from premature termination. A safe termination strategy developed for Turbo codes is generalized to layered LDPC decoding. Then, a more efficient version and also two less efficient, but less complex, criteria are proposed.File in questo prodotto:
