Abstract :
Error-correcting turbo codes suffer from an error floor at moderate to high signal-to-noise ratios. The error floor results from the relatively low free distance of the code caused by the poor mappings of the pseudo-random interleaver. A method for eliminating bad interleavers is proposed, thereby improving the code performance
