Novel bispectrum-based signal processing technique is proposed for analysis of turbulence contained in the atmosphere. Novel classification features evaluated in the form of bicoherence estimates of the weather radar signals backscattered by volume-distributed atmospheric formations are suggested for solving the discrimination problem of the safe laminar meteorological formations and zones of turbulence...
This paper is devoted to a novel multi-frequency and bispectrum-based encoding technique designed for radio communication systems. An experimental study of an interference resistance in digital communication is performed using a novel bispectrum-based strategy. Test statistics evaluated in the form of peak values of magnitude bispectrum estimates are proposed for triplet-signals discrimination. Bit...
The methods of smoothing of the bispectral density estimate when solving the problems of restoration of signals with an unknown shape in the interference environment and random signal delay are considered for the first time. The performed analysis of statistical characteristics of noise that presents in the bispectrum estimate shows that these statistical characteristics have a rather complex unsteady...
Micro-Doppler (mD) radar is an efficient tool for surveillance systems and they are rapidly developing now. One reason for this is the potential ability of mD radars to provide additional information (features) useful for recognition of objects extracted from short-time spectral or higher-order estimates. In particular, it is known that a signal reflected from a walking human represents a set of harmonics...
