A methods comprising a hybrid early-termination strategy and an output selection procedure for iterative decoders are disclosed. The hybrid early-termination strategy combines the output-comparison-based method with the CRC-check-based method. The hybrid approach is far more superior in termination reliability in either of the two individual approaches, without their disadvantages. The hybrid termination strategy effectively and reliably terminates the iterative decoding process, cutting the majority of the computational load while eliminating the degradation in the bit error rate (BER) and frame-error-rate (FER) performance due to incorrectly terminated frames. The output selection procedure chooses the best possible decoded frame among those from all iterations, eliminating the iteration abnormality that is inherent in the iterative decoding approach, and improving the BER performance of the standard iterative decoders.
