The invention discloses a dynamic decoding method of Vitby, including: Vitby algorithm for decoding the receiving and decoding, the sequence based on the set parameters, the parameters including memory depth and / or memory width, the memory depth is the grid map of Vitby algorithm, backtracking and / or the memory span width is branch grid map algorithm in the Vitby metric on the parameter value is adjusted in the range of lower and upper limit of adjustment adjustment, to decode the received sequence under a Vitby algorithm to adjust the parameter value after. The invention also discloses a dynamic Viterbi decoding device. By adopting the present invention, the decoding parameters can be dynamically adjusted according to the current channel noise, the decoding performance of Vitby can be maximally exploited, the error rate can be effectively reduced, and the effective utilization of resources can be ensured.
