Abstract
In this article, we propose a new stopping criterion for turbo codes. This criterion is based on the behaviour of the probabilistic values alpha 'α' calculated in the forward recursion during turbo decoding. We called this criterion Sum-α. The simulation results show that the Bit Error Rates BER are very close to those of the Cross-Entropy CE criterion with the same average number of iterations.
