Abstract
In one embodiment, device for early stopping in turbo decoding includes a processor configured to receive a block of data to be decoded, compare hard decision bits resulting from decoding iterations and compare a minimum value of log likelihood ratio (LLR) of decoded bits against a threshold. The processor configured to match hard-decisions with previous iteration results. The processor may be configured to set an early stop rule after the matching hard-decisions with previous iteration results is matched. The processor may be configured to set an early stop rule when the minimum reliability of the output bits exceeds the threshold.
