摘要：A method and apparatus for normalizing a plurality of state-metric registers ina decoder using a trellis. The method includes determining an approximate minimum ofrespective state-metric values stored in the plurality of state-metric registers, andsubtracting the approximate minimum from the values. Determining the approximateminimum preferably includes determining the minimum of a predetermined number ofmost significant bits in the plurality of state-metric registers.
