Improved impulse method to evaluate the low weight profile of sparse binary linear codes
David Declercq, M.P.C. Fossorier · 2008
In this paper, the impulse method to determine the low weight profile of sparse codes is improved based on efficient probabilistic approaches for reliability based decoding that are adapted to this problem. As a result, compared with previous approaches, the same low weight profile can be obtained with a significant time reduction (for example from 30 hours to a few minutes) or more complete low weight profiles can be determined in the same amount of time.
