Abstract
Method and decoding device for decoding a convolutionally coded input data signal y. The input data signal is multiplied with a scaling factor L() and then demultiplexed (). The demultiplexed input data signal LS is then turbo decoded () in order to obtain decoder output likelihood ratio data Λ. The scaling factor Lis updated () for a next iteration in dependence on a combination of a posteriori likelihood data based on turbo decoded output data Λ and a priori likelihood data based on the demultiplexed signal LS.
