此代码的功能是实现网络纠错当中的循环冗余码纠错法，即输入一个初使二进制比特流与生成多项式可以得出一个拥有循环冗余纠错码的二进制比特流，此比特流如果转输到目的地就可以进行差错验证了，以保证代码的正确传输。代码注释里有详细的测试数据与说明。-This code is a network error-correcting function among the cyclic redundancy code error correction method, that is early to make a binary input bit stream generator polynomial can be drawn with a cyclic redundancy error correction code with a binary bit stream, this bit flow to the destination if the transfusion errors can be verified to ensure the correct transmission of the code. Code comments are detailed test data and instructions.
