VLSI Viterbi decoder with branch metric unit

The Viterbi decoder has a back-trace mechanism and is implementable in a VLSI circuit. It contains a branch metric unit to determine path weight values, and addition-comparison-select unit to determine new path weight values, a minimal path metric unit, a temporary store and a back-trace unit.The de...

More Information
Summary:The Viterbi decoder has a back-trace mechanism and is implementable in a VLSI circuit. It contains a branch metric unit to determine path weight values, and addition-comparison-select unit to determine new path weight values, a minimal path metric unit, a temporary store and a back-trace unit.The decoder contains a first data store (1400). Last in first out device, a first tracking logic unit (1402), a second store (1404), a second tracking logic unit (1406) and a third data store (1408).
