Abstract
A blind recognition method of self-synchronized scrambler is proposed for the case that self-synchronized scrambler input sequence is RS code. Firstly, equivalent block code length of the RS code is recognized through scrambler sequence. Then, the extracted scrambler sequence is obtained by using possible polynomial of the scrambler. Based on the different linear constraint between the results of correct and wrong sequence extracting, the polynomial of the scrambler is determined by a new entropy difference of zero elements after matrix elementary transformation. Simulation results show the effectiveness of the blind recognition method of the self-synchronized scrambler after the Reed-Solomon code.关键词
