Convolution Code Identification and Codeword Synchronization Based on Parity-Check Matrix

The matrix representation of convolution code and the relation between generation matrix and parity-check matrix are introduced briefly.Thus a new method of identification of convolution code based on the transcendent knowledge of parity-check matrix is presented.The method helps identify the type of convolution code and synchronize the codeword of sequence obtained in the communication detecting system through the parity-check matrix and it's relation with the data sequence received.The method makes the next step of decoding flexible and is validated by simulations conducted under the conditions that there are errors in the received data sequences and that there are not.
