| Abstract: | By comparing neighboring decision data, an improved algorithm for Viterbi decoding is proposed. A performance analysis is conducted both for traditional and improved algorithms through a theoretical calculation and corresponding numerical solution is given. The decoding property is compared through computer simulation. The results of theoretical analysis and the simulation demonstrate that the performance of decoding is raised to certain degree. |
