Research on RM code feature analysis

For the feature analysis problem of RM code, the generator matrix of the equivalent system code is determined by linear transformation, thereby determining the code length and information length of the analyzed codeword, combining the constraints on the row weight of the generator matrix, assuming that the analysis data is RM coded, the RM code order is obtained, and the generator matrix of the RM code is obtained.If the generation matrix of the equivalent system code can be obtained by linear combination of the generator matrix of the RM code, it can be confirmed that the RM code is used and the generator matrix is solved correctly. The experimental simulation shows that the recognition result of the coding parameters of the actual data is exactly the same as the premise of the RM code encoded data sequence, which indicates the correctness of the analysis method.
