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.
