摘要： In a digital system using a turbo code, a method for performing iterative decoding in accordance with a Log-MAP Algorithm comprises the steps of: generating a look-up table comprising a plurality of values representative of a correcting factor; performing a first calculation to obtain a forward metric; performing a second calculation to obtain a backward metric; performing a third calculation to obtain a log-likelihood ratio for every information bit to be decoded. In accordance with the method, at least one and no more than two of such calculations are performed by the use of said look-up table for implementing the Log-MAP decoding algorithm and the remaining calculations are performed implementing a Max-Log-MAP decoding algorithm.
