| Abstract: | The principles of conventional Viterbi decoding algorithm are introduced in this paper.Based on the coding principle of convolutional codes and the subnet list of(2,1,7)codes,an improved Viterbi decoding algorithm is proposed.The results of simulation proves the feasibility of this algorithm.The data analysis shows that the memory need and the decoding delay are reduced obviously after using this algorithm.This algorithm is also feasible to other convolutional codes. |
