摘要：
This paper researches an algorithm about the blind recognition of systematic convolutional code. By building data matrix and analyzing the rank property of the matrix, the algorithm can realize the blind recognition of channel parameters, including the code length, code beginning, code rate, checking polynomial, as well as the generating polynomial. This paper also proposes the idea to transfer the algorithm to digital signal processor (DSP). After transferring the software codes onto the hardware platform, we optimize the algorithm in the software Software of Code Composer Studio (CCS) and then finish the simulation of the blind recognition of systematic convolutional code with code rate equals 1/2. It offers support to the fast implementation of the algorithm in actual projects.
