A New Stopping Criterion for Duo-binary Turbo Codes

This paper describes a novel stopping criterion for duo-binary turbo codes. The correlation between the two bit-level extrinsic information increased as the performance improved by the iterative decoding. In this way, the new method reflects a more reasonable solution for symbol-level decoding of duo-binary turbo codes. Simulation results showed that the proposal criterion was able to reduce the average iterative decoding number with a good error performance as compared to conventional criteria.
