Abstract
Official abstract text for this publication.
A system is to receive a word on which to perform error correction; obtain segments, from the word, each segment including a respective subset of samples; update, on a per segment basis, the word based on extrinsic information associated with a previous word; identify sets of least reliable positions (LRPs) associated with the segments; create a subset of LRPs based on a subset of samples within the sets of LRPs; generate candidate words based on the subset of LRPs; identify errors within the word or the candidate words; update, using the extrinsic information, a segment of the word that includes an error; determine distances between the candidate words and the updated word that includes the updated segment; identify best words associated with shortest distances; and perform error correction, on a next word, using other extrinsic information that is based on the best words.
First claim
Opening claim text (preview).
What is claimed is: 1. A system comprising: one or more devices to: receive a word, of a block of words within traffic, on which to perform forward error correction, the word including a group of samples, each of the group of samples including respective encoded bits and respective reliability bits, the respective reliability bits corresponding to a respective level of reliability of the respective encoded bits, obtain, from the word, a plurality of segments, each segment, of t…
