代码说明：

   generates the output sequence of a binary convolutional encoder G : N x LK Generator matrix of a convolutional code K : Number of input bits entering the encoder at each clock cycle. input: Binary input sequence state: State of the convolutional encoder termmode= trunc for no termination with all-0 state Copyleft: Won Y. Yang, [e-mail], CAU for academic use only X = Known frequency-domain training symbol y = Time-domain output of the channel H_est = Estimate of the channel response
