Abstract
An apparatus (800) processes a data stream of convolutionally encoded information and generates decoded information using a series of symbol selections that potentially correspond to at least a portion of the data stream (610, 620). A first reliability indication is obtained for a particular decision made for a symbol selection (630). When the reliability indicator does not satisfy a particular criteria, a traceback is performed along the series of symbol selections to develop a second reliability indication based on whether, after adjusting for allowable error patterns, an alternative set of symbol selections yields the decoded information within a predetermined number of symbol selections (635, 640, 645, 650, 655, 660, 665). An action is taken based on the second reliability indication (670).
