Abstract :
Near Shannon limit error-correcting coding and decoding - turbo codes were proposed in 1993 and lots of work was done on this aspect. Several adaptive iterative decoding algorithms for turbo codes were proposed to reduce the decoding delay. We investigate and improve these adaptive algorithms. The simulation results, comparison and analysis are presented
