Safe Early Stopping for Layered LDPC Decoding
Marco Ferrari, S. Bellini, Alessandro Tomasoni · IEEE Communications Letters · 2014
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.
