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.
