We consider a method based on the generalized maximum-likelihood rule for solving the problem of reception of the signals with orthogonal frequency division multiplexing of their harmonic components (OFDM signals) in the time- and frequency-scatterin

New methods of symbol-timing and carrier-frequency blind synchronization of an OFDM-signal receiver are developed and studied. They generalize the well-known methods which use either the protection interval in time in the cyclic prefix form or the pr

Using the mathematical tool of high-order spectra (polyspectra), we consider the synthesis of optimal variants of high-order differential phase-shift keying in the frequency domain. The proposed approach allows all possible variants of the second-ord

We propose a criterion of resolution of one-type incoherent signals with respect to two scalar parameters and estimate the corresponding resolution limits.

We perform a laboratory study of the nonlinear phase relation between short gravity waves with wavelengths of the order of 10 cm and their higher harmonics including “spurious” capillary ripple. The presence of higher harmonics of the basic low-f

A method of synthesis of quasideterminate bispectrally organized signals for the calibration, simulation, sounding, and parallel transmission of large databases is presented. As the elementary structural unit of a complex information signal, we chose

We analyze the physical limits of sensitivity of bispectral receivers (bispectral analyzers) due to the background level of the bispectrum of their own thermal noise. The potential sensitivity of a bispectral receiver, compared with the spectral anal

Changes in the rheoencephalogram (REG) obtained for cosmonauts on the first and second expeditions during their time aboard the orbiting station, Salyut-4, are described. REGs were recorded by a small apparatus, Levkoi-3, with subsequent transmittal
