Channel coding identification is often required in modern digital communications. As the existing blind identification methods for RS code are complicated for the reason that all spectral components in high-order domain need to be calculated

a method based on binary equivalence is proposed. Firstly

RS code is equivalent to binary linear block code according to finite field properties

with the establishment of the association model between code length

information block length

generator polynomial and primitive polynomial. Then

the various parameters of RS code are identified by traversing primitive polynomials and verifying parity check vectors of the binary linear block code. Simulation results and theoretical analysis show that the proposed method can improve error-resilient performance and reduce computation cost as well

which proves its availability in intelligent communication and communication reconnaissance systems.
