Aiming at solving the problem of recognition for the type of linear block code and the convolutional code, a method of the channel coding type recognition based on the run feature is proposed. Namely, the difference of the run feature of the linear block code and convolutional code is analyzed in theory. It shows that the randomness of the convolutional code run feature is superior to that of the linear block code, and the linear block code run number around the information bit length has a certain amount of distortion. Therefore, the code type can be identified by abstracting the run feature of these two codes. Simulation results show that the proposed method has high robustness and accurate recognition, and the method has a certain value in future engineering application.
