摘要

Systems and methods for turbo iterative decoding of low error rate and low complexity. The invention relates to an iterative turbo decoding method of low error rate and low complexity characterized in that it comprises (a) the storage of the llr metrics in an input memory bank that subsequently delivers, or the block corresponding to a decoder does not parallel that works forward (fw) and backward (bw), well the sub-blocks corresponding to two or more parallel decoders fw/bw; (b) the calculation of a-posteriori metrics by the decoder (s); (c) the calculation by one or more extrinsic calculation units of the extrinsic information; and (d) the comparison of llr measures a-posteriori fw and bw along different iterations. The invention refers to different implementations of the method as well as systems that implement said method and its variants. (Machine-translation by Google Translate, not legally binding)
