In order to solve the problem of the blind recognition of BCH codes,a novel method for fast detection of the BCH parameter identification based on the Statistical significance is presented. Some analytical models for BCH codes are proposed by analyzing the distribution of BCH code roots.The check matrix is constructed by using the obtained length and code roots of BCH codes with the help of completing shortened codes.Finally the BCH generator polynomial can be calculated directly by simplification of matrices in the finite field. Simulation results illustrate that given the high BER BCH encoded data sequence, the recognized coding parameters are correct by comparing prior conditions, which validates the accuracy of the proposed method.

Key words: BCH codes, parameter identification, primitive polynomial, generator polynomial
