Abstract:A novel method based on Euclidean algorithm is proposed to solve the problem of blind recognition of binary Bose-Chaudhuri-Hocquenghem (BCH) codes in non-cooperative applications. By carrying out iterative Euclidean divisions on the demodulator output bit-stream, the proposed method can determine the codeword length and generator polynomial of unknown BCH code. The computational complexity is derived asO(n(3)). Simulation results show the efficiency of the proposed method.
