Abstract In view of the fast development of information countermeasure and intelligent communication, recognition of channel coding has been a vital issue in information interception. This paper proposes a new method of recognition in order to recognize the (n,1,m) convolutional codes. Firstly, this method defines the notion of check-sequence, and solves it by an advanced model of matrix, then deduces the matrix of generator polynomial, having recognized the convolutional code, by check-sequence. Finally, examples of simulation show that this method is able to recognize, neither knowing the parameter of code n nor the begin location of coding, all (n,1,m) convolutional codes effectively.
