Abstract:
A method and device for performing forward error (FEC) correction avoidance based upon predicted block code reliability in a communications device is provided. An avoidance unit comprising a metric computation unit and a decision unit generates a reliability metric based upon a received code block. The reliability metric is compared to a reliability threshold, and the forward error correction decoder in the communications device is disabled if the metric is below or equal to the threshold.
