Iterative decoding process

摘要

A method of iteratively decoding a block of information based on a predetermined error detection structure is provided, The method includes: a) performing a sequence of iterations for decoding the block of information to produce a decoded output in each iteration; b) producing from the decoded output, and the predetermined error detection structure, a reliability metric for the respective iteration, which reliability metric is based on said predetermined error detection structure; and c) utilizing the reliability metric as a criterion in an abort decision with respect to further iterations of decoding the respective block of information
