Disclosed are a Viterbi decoding method and apparatus for high speed data transmissions. Branch metric is used with data inputted from a Viterbi decoder used in a communication system, and, when current state metric is used for addition, comparison, and selection, the selection operation is performed after simultaneous addition and comparison operations are performed, so that a faster decoding processing speed is obtained. The decoding process is carried out at a high speed with the addition and comparison operations carried out simultaneously, thereby preventing the increase of power consumption.
