Abstract
Methods and apparatus are provided for processing a plurality of data blocks. In accordance with embodiments of the invention, a correction flag for each of the data blocks can be received, along with information on at least one error event for each of the data blocks. Using this received information, a search trellis corresponding to the data blocks can be determined. Determining the search trellis can include determining a plurality of branches and computing a branch metric for each of the branches. A search on the search trellis can be performed to identify at most one error event for each data block, where the search is based on the branch metrics.
