PURPOSE: A method for calculating the traceback of a Viterbi decoder is provided to save the capacity of the memory in comparison with a conventional method without performance deterioration. CONSTITUTION: A method for calculating the traceback of a Viterbi decoder includes the steps of: a first step of constructing a traceback block by a predetermined number of memories with a capacity having a half of the conventional unit memory in the Viterbi decoder; and a second step of performing the traceback by two memories simultaneously when the Viterbi decoding is performed by using the memories.
