Abstract
The existing blind recoginition methods of cyclic code have poor effects in the high or only Bit Error Ratio(BER) better in low code rate conditions,or the method is only for a subclass of the cyclic codes.In order to solve the blind identification for cyclic code with high BER or high code rate effectively,a method based on code weight distribution and matrix transformation was proposed.First of all the article structured the receiving sequence to matrix according to the estimated code length,and then realized the blind recognition using the improved weight distribution distance formula.The simulation results show that the method can realize the blind recognition for cyclic code with high BER and high code rate,and the results are better.
