This study proposes a novel multi-fractal spectrumbased approach to distinguish linear block codes from its selfsynchronous scrambled codes. Given that the linear block code and self-synchronous scrambled linear block code share the property of linear correlation, the existing linear correlation-based identification method is invalid for this case. This drawback can be circumvented by introducing a novel multi-fractal spectrum-based method. Simulation results show that the new method has high robustness and under the same conditions of bit error, the lower the code rate, the higher the recognition rate. Thus, the method has significant potential for future application in engineering.
