| Abstract: The paper Present a new receiver for detection of covert M.sequence regardless the chip code sequences and the type of modulation. A Higher Order Statistics (HOS) based on the Kurtosis of the received signal is used to classify the type of the modulation, and so decide the modulator. The Triple Correlations Function (TCF) of M. sequence of the demodulated which differs from sequence to another according to the feedback connection is used to decide the generation function g (x) from the peak position of this M-sequence. This paper is classified into four sections the first section, we introduce some property of modulation and how the (TCF) of the M.sequence generated. Secondly, the digital modulation classification is classified and tabulated using theoretical cumulants Statistics C40, C42. The Triple Correlation function (TCF) of M.sequence is showed in section three. Computer simulation of determination of feedback polynomial y(x) at section four. Finally, the conclusion is presented in at the rest of this paper. | ||
