中文说明：卷积编码，Viterbi译码：维特比算法并不是只针对卷积码的，可以说，它是一个普适的有限状态机算法(LSM)。只要有一个LSM，能够受不同输入的触发，在各个状态间跳转，并产生输出，就满足可基本条件，可根据状态机利用Viterbi 来从污染的输出中还原输入。
English Description：
Convolutional coding and Viterbi decoding: the Viterbi algorithm is not only for convolutional code, it can be said, it is a universal finite state machine algorithm (LSM). As long as there is a LSM. To enter a different trigger, jump in each state, and produces as output, satisfy basic conditions, according to the state machine using Viterbi from the output of the pollution reduction input.
