对于任何给定的卷积码，由于截断维特比译码中的路径长度的比特错误概率的上限。然后使用该界限来确定与最大似然解码错误概率相比由于截断而导致的附加错误概率变得可忽略的路径长度。这些结果进行了测试模拟使用几个短的约束长度的代码。
An upper bound on the bit error probability due to truncation of the path length in Viterbi decoding is obtained for any given convolutional code. This bound is then used to determine the path length at which the additional error probability due to truncation becomes negligible compared to the maximum likelihood decoding error probability. These results are tested by simulation using several short constraint length codes.
