这里实现的卷积码译码器可实现（n,1,K）的卷积译码，即一个输入码元，n个输出码元，编码器的约束长度为K，采用函数的默认值将实现（2,1,7）的卷积译码。译码方法为维特比硬判决译码，且译码开始状态假定为全零状态。(Here to realize convolutional code decoder can realize (n, 1, K) convolutional decoding, namely an input element, n output element, encoder constraint length is K, takes the default value of function, achieve the convolutional decoding,1,7 (2). Decoding method for decoding victor than hard decisions, and decoding the start state assumed to zero state.)
