Properties of the Tailbiting BCJR Decodersists of forward and backward recursions that start from the left and right principal eigenvectors of the product of the trellis gamma matrices. The result is a slightly sub-optimal symbol-by-symbol MAP decoder that performs much less computation than the true MAP decoder. The decoder has both itera

Iterative Decoding of Tail-Biting Trellises and Connections with Symbolic Dynamicsrithms on tail-biting (TB) trellises..The convergence of the sum-product algorithm on tail-biting trellises was analyzed recently by Anderson and Hladik [2] and was shown to give approximate a . probabilities..We introduce and analyze generating function versions of both algorithms, each involving a

Algorithms for Decoding and Interpolationnd the Welch-Beriekamp algorithm. We focus on relationships of these algorithms with interpolation methods in system theory. We note that the problem statements in the two areas can be different: from a system theoretic point of view, rational interpolating functions with common factors between nume

We determine the limiting behavior as x → 0 of the result of the generating-function sum-product algorithm and show how this relates to maximum-likelihood sequences and the generating-function min-sum algorithm.
