Abstract

A convolutional decoder for a wired or wireless receiver receiving an encoded datastream. The branch and path metric components compute branch and path metrics for the encoded datastream stream. The traceback unit couples to the path metric component to trace in each traceback interval a single path through the path metrics to determine correction factors for decoding at least two corresponding successive sub-symbols/symbols from the encoded datastream in each traceback interval.
