摘要
A method for decoding a transmitted data sequence using a full-length decision window, such as in a trellis decoder, in which transition paths have converged. Transition paths within the decision window and their associated soft values are compared with a stored candidate for the next best path and associated stored soft value. Based on the comparison, and whether the transition paths and the best path have merged during the decision window, the decision window is shifted or the stored candidate for the next best transition path and associated stored soft value are replaced by the possible candidate for the next best path and associated soft value. The decision window is then shifted.
