A simple technique to control transient chaos in the turbo-decoding algorithm, which improves the performance of classical turbo codes, is developed. On average, the turbo-decoding algorithm with control (when stopped after eight iterations) shows a gain of 0.25-0.3 dB in the practical signal-to-noise ratios (from 0 to 1 dB), compared to the classical turbo-decoding algorithm without control
