说明：  本程序是卷积码的维比特译码，本例中使用的是循环反馈卷积码，最后状态不归零，与我的另一个程序不同，我采用编码控制回零，解决归零问题！最后状态回零！各项指标良好！
(This program is Wei Bite decoding convolutional codes, in this case using a circular feedback convolutional codes, the final state is not zero, and my other procedures are different, I used the coding control back to zero, zero to solve the problem! Final state back to zero! Good indicators!)
