A Method of Blind Recognition of Cyclic Code Generator Polynomial

In this paper, we first introduce the description of the cyclic code, and according to the features of the cyclic code, build the generator polynomial recognition model in the scenario of coding length known, and then propose an iterative algorithm to reduce the computation complexity; on this basis, through the analysis of the coding frame structure, we build the generator polynomial recognition model and the similar iterative algorithm under the condition of coding length is unknown and frame length is known. Finally, we use two examples to illustrate the recognition procedure and verify the recognition algorithm.
