卷积码（2，1，3）编码过程。代码清晰简单，对应人民邮电版《通信原理》中卷积码编码过程-Convolutional code (2,1,3) encoder. Code is clear and straightforward, Telecommunications for the corresponding version of " Communication Principle" in the process of convolutional coding

In this case is a convolutional encoding code for decoding the convolutional code, using VHDL language. This code provide the method of convolutional encoding for input data. (2,1,7)
