Abstract
A method for reducing the number of error events in a transmitted data stream (34) comprises the steps of (i) generating at least a first most probable sequence (16(1)) and a second most probable sequence (16(2)) with a detection algorithm (12); (ii) determining if a first correctable error occurred in the first most probable sequence (16(1)) with an EDC decoder (14); and (iii) determining if a second correctable error occurred in the second most probable sequence (16(2)) with the EDC decoder (14). Additionally, the steps of determining if a first correctable error occurred and determining if a second correctable error occurred can be performed substantially simultaneously. The method can further comprise computing a plurality of path metrics (42) for the transmitted data stream (34); and selecting a first q smallest path metrics out of the first and second most probable sequences (16(1)), (16(2)) with a Q value selector (44).
