摘要

Systems and methods for turbo iterative decoding of high bit rate, low error rate and low complexity. The invention relates to a method for turbo decoding in parallel series iteratively high bit rate, low error rate and low complexity comprising using metrics path (PMs) in the right edge of the sub-blocks as metrics initialization for the next sub-block of the next iteration; and using states of the road (ML) of the left edge of the sub-blocks to the last backward travel (TB) from a previous state of reliable SOVA decoder, said interchangeable MLs in the same iteration. The invention also relates implementations of the method based on SOVA and BISOVA algorithms as well as an implementation based on a new algorithm, Alšova, as a change of SOVA and systems implementing such methods.
