摘要

Systems and methods for turbo iterative decoding low error rate and low complexity. The invention relates to a method of turbo iterative decoding of low error rate and low complexity comprising (a) storing the LLR metrics in a memory bank input later delivery, while the corresponding block to a decoder not parallel working forward (fw) and backward (bw) or the sub-blocks corresponding to two or more parallel decoders fw / bw; (B) calculating a-posteriori metrics or by the decoders; (C) calculating one or more units of extrinsic calculation of extrinsic information; and (d) comparing the measures a-posteriori LLR fw and bw along different iterations. The invention relates different implementations of the method and systems implementing the method and its variants.
