Novel blind recognition method for self-synchronized scrambler
Lu Gan · Journal of Communications · 2013
In non-cooperative communication systems,an adversary has to blindly estimate the coding parameters of scrambler from intercepted sequence.On the condition of biased information source,a new method was proposed which can blindly recover the generating polynomial of self-synchronized scrambler.This method was based on the corrected squared Euclidean distance which was used to measure the distance between the actual statistical probability and the uniform distribution.The simulation results verify the theory analysis and the validity of the algorithm.
