....In recent years, a number of new graphical models have emerged in coding theory, and evolved into a far reaching general framework for representing a code by a graph. In this context, one encounters various generalizations of a trellis, such as tail biting trellises [22] and trellis formations [49, 50], as well as Tanner graphs [71] that are in some sense diametrically opposite to trellises. All these representations are special cases of the general concept of a factor graph. We refer the reader to [1, 37, 38, 79] for a detailed treatment of factor graphs and the associated iterative ....
