Abstract :
In this paper we combine techniques for early stopping and error detection in order to stop the iterative turbo code decoding process and detect if errors are present in the decoded bit sequence. The simple and efficient approaches we introduce are based on monitoring the mean of the absolute values of the log-likelihood ratios at the output of the component decoders over each frame
