| 摘 要： | 改进后的Viterbi译码算法，不但保持了原有Viterbi算法的特性，而且在减少译码路径的情况下，较好地解决了突发错误信道中原Viterbi译码算法性能急剧下降的问题．通过在编码信道模型上的仿真表明：正确的约束位越多、分布的越密，则性能提高越明显．

| Abstract: | Viterbi algorithm decoding is a kind of maximum likelihood decoding.In this paper,the improvement of Viterbi algorithm is produced.The experiment results show that it can overcome the drawback of the decoding performance greatly degraded,when burst errors occur,and reduce the decoding complexity while the good characteristic of conventional Viterbi algorithm remains uncharged.Simulations over coding channel show that the more correct bits we know the better the performance is. |
