- Abstract
- This article presents calculations and results of mathematical modeling for the development of a covert information transmission channel based on Lobachevsky pulses with overlapping Fourier spectra. The necessary conditions for orthogonality and orthonormality are defined, and the autocorrelation and spectral characteristics of the pulse signals are investigated. Methods to reduce the unevenness of the Fourier spectra of Lobachevsky pulses using window functions are proposed. The interrelationship between the parameters of Lobachevsky pulses and the Kotelnikov theorem, as well as the selection of processing algorithms, structure, and parameters of pulse signals for constructing a covert communication system, are discussed.
