A method for blind identification of rate 1/2 convolutional code based on improved Euclidean algorithm

Abstract

In order to adapt the characteristic that the intercepted code sequence is not complete, the polynomial model in [6] has been amended. Based on the model, a scheme is proposed to improve the capability of classical Euclidean algorithm, and a new method for blind identification of rate 1/2 convolutional code is proposed. The validity of algorithm is verified by the simulation results, and it has less computational load compared to the references.
