Abstract
The invention provides methods and systems for terminating an iterative decoding process of a Forward Error Correction block (FEC). The iterative decoding process of the FEC block is terminated upon determining that the FEC block cannot be decoded successfully. A method comprises calculating a metric based on one or more Log Likelihood Ratios (LLRs) corresponding to a first number of iterations of the iterative decoding process of the FEC block. The method further comprises, formulating one or more stopping criteria for the iterative decoding process based on a variation pattern of the metric over a second predetermined number of iterations of the iterative decoding process. The second predetermined number of iterations is a subset of the first number of iterations. Moreover, the method comprises terminating the iterative decoding process of the FEC block based on the one or more stopping criteria.
