As a result of the project: the theory of formation, transmission, detection and differentiation of digital bispectral-organized signals is created; developed noise stability towards additive and impulse noise, fading effects and hardware phase fluctuations (jitter) in the communication channel bispectrum-organized methods of modulation based on orthogonal synthesis bispectrum-organized triplet-signals and their differentiation through new test statistic of order - estimates of peak magnitudes of bispectral density; the methods of generating signals polyfrequency triplet-based precision multifrequency oscillatory systems robust to destabilizing factors. Obtained as a result of the project, new conceptual provisions, approaches and methods are fundamental to the theory of potential impedance of digital signal transfer systems, the theory of self-oscillating systems, nonlinear spectral analysis of signals, synthesis of multi-frequency quartz oscillation systems for generation of triplet signals. The implementation of the proposed noise immune bispectral-organized methods of modulation and signal processing is appropriate and is promising in the automated radar detection systems for moving ground and air targets; radar alarm systems, military radiotechnical systems for observing and recognizing mobile ground objects in conditions of increasing requirements for increasing Ukraine's defense capability   Product Description popup.authors Goroshko Andriy V.
