M. Kokkonen et K. Kalliojarvi, Soft-decision decoding of binary linear block codes using reduced breadth-first search algorithms, IEEE COMMUN, 48(6), 2000, pp. 905-907
This letter discusses soft-decision decoding of binary linear block codes u
sing the t-algorithm and its variants. New variants of the basic algorithm
are presented that reduce decoding complexity using a threshold adaptive to
the signal-to-noise ratio and address the variable decoding complexity by
either limiting the memory or using a generalized M-algorithm with a noncon
stant state profile.
