simplified method for standardization of alpha - and beta metric in the turbo decodeurs

摘要

method for normalizing metric "before" (alpha) in the siso (soft input decoding units of turbo decoders, soft output) by subtraction at each point k of netting a metric normalisation "alpha (k, na)", "so any mesh the metrics before normalization "alpha (k, s) to states' such as' s s0u00bb mesh.application to systems using turbo codes, and in the area of telecommunications, including the wired access network, wireless local loop, the radio mobile communication systems, optical communication systems and communication at short range, and in the field data storage (magnetic tape, disk, cd-rom, dvd, etc.). (see figure 5).
