It is shown that the Prony and matrix beam methods of exponential approximation, which recover the function image basing on a time-solution (an original), and the numerical method of the Laplace-Pade inverse transformation can be considered as a pair of direct and inverse Laplace numerical transformation. The simulation examples of dynamic systems by the combined Prony-Laplace-Pade and matrix beam methods in the time and frequency domains are presented, which are typical for tasks of the circuit theory and radio-electronics. In particular, radio pulse passage with the intra-pulse angular modulation is investigated; the systems with phase and frequency shift keying are studied. The matrix beam method is used to lower the approximation order of circuit functions with a given error value.

The existence of artificial structures in the aquatic environment, in particular, oil and gas producing structures, necessitated continuous monitoring of their behavior and, accordingly, autonomous sensors capable of accumulating and transmitting information to processing points. The use of ultrasonic and radio engineering technologies for underwater data transmission does not primarily provide the required transmission speed. The transmission speed can be significantly increased if electromagnetic waves of the optical range are used as carriers. Analytical methods are often used to evaluate the characteristics of hydrospheric optical communication channels, in particular attenuation, but such methods do not take into account many features of the propagation of optical radiation in the hydrosphere. For example, the Lambert-Beer law used to calculate the channel attenuation cannot be used in a medium with high turbulence. The article presents a statistical model of the optical wave propagation based on the Monte Carlo numerical simulation method. This channel model can be used to estimate the spatial and temporal distribution of photons, communication range, taking into account both unscattered photons and single scattered and multiple scattered ones. The simulation results can be used to predict various design parameters of underwater optical communication systems.

This article discusses the effectiveness of the application of the algorithm for blind separation of two real signals in the problem of detecting a reference signal with an additive white Gaussian noise. As a detection criterion, the ratio of the maxima of the posterior probability densities is used: if the reference signal is in the sample and in its absence. The article contains a graph of the dependence of the detection criterion of the reference signal on the signal to noise ratio. A narrowband signal with constant parameters is used as a reference signal.

Currently, existing methods for evaluating the network performance of packet-switched networks are based on monitoring the excess of the values of network performance indicators of predetermined threshold values. At the same time, maximum, minimum and average values of indicators are widely used. In such operations, it is not taken into account that if the values of the indicators are in the range of permissible values, then the quality of the network connection is considered acceptable. It is most advisable to take into account the magnitude of the deviation of the indicator values from the areas of permissible values and the duration of such deviations. In this case, the deviation value will characterize the amount of network performance degradation, and the duration of the deviation will characterize the duration of the performance degradation. The network performance assessment thus formed will closely characterize the perception of the quality of the communication service by the user of the communication service. This article focuses on the development of such network performance metrics.

A system of ultra-wideband communications is considered, in which both transmitter and receiver are multielement devices composed of $N$ UWB direct chaotic transceivers, operating in collective mode. The transmission side of the system was investigated earlier, and the structure of its emission field was analyzed in details. Collective information transmission with $N$ independent, yet synchronous ultra-wideband chaotic transmitters increased signal-to-noise ratio at the receiver input by a factor of $N$. Here, a multi-element energy receiver (ensemble of envelope detectors) is investigated analytically. As is shown, the use of $N$-element receiving system increases the output signal-to-noise ratio by another factor of $N$. Thus, the overall effect of $N$ transmitters plus $N$ receivers is an increase of the output signal-to-noise ratio by a factor of $N^{2}$, which means $N$-times larger communication distance.

The article presents the research results on generalization of three-circuit oscillatory systems (OS) classification, including the case when the time constant of the intermediate circuit $tau_{2}$ varies from finite values up to zero, which means that the coupling between the circuits is resistive. It is proved that the bifurcation diagram of the OS loci can be divided into 10 regions that are topologically similar for any $tau_{2} > 0$. At $tau_{2} =0$, there remains the only boundary of $gamma$-type, which separates the loci of hysteresis and non-hysteresis types. In this case, as the whole diagram shows, the OS resonance points are locally stable if they are located to the left of the $gamma$-boundary and globally stable to the right of the boundary. The results obtained are important at the OS parameters' choose with account contradictory requirements to the loading power, steady-state stability, frequency and phase stability, etc.

The results of the analysis of the autodyne response of microwave oscillators, which are under the influence of both their own microwave radiation reflected from the target and the signal from an external oscillator, are presented. The basic relations for the analysis of the autodyne response are obtained under the condition of asynchronous external influence when the oscillator is in the regime of quasi-harmonic beats. The signal characteristics of the autodyne were calculated. Experimental data were obtained on the Ka-band Gunn-diode oscillator. There is showed the oscillograms of the autodyne signals obtained at the output of the amplitude detector for the cases of the beat signal frequency appears 5 MHz and 0, 2 MHz.

The present paper describes the design of an ultrawideband circular antenna array for direction finding applications. The proposed antenna array consists of nine identical biconical dipoles, has a diameter of 522 mm, its operation frequency band is 0.3–3 GHz. Numerical and experimental results for biconical antenna under study are presented. A special feature of the proposed array element design is the possibility of its production by cheap laser-cutting technique and its modular construction. The key criteria for selecting an element for implementing the direction finding antenna array is the antenna factor. Influence of mutual coupling and shading effect in the antenna array have been also estimated.

Research addressed the problem of increasing the transionospheric communication channel capacity after adaptive compensation for frequency dispersion when total electron content of the ionosphere is measured with a stochastic error. To estimate that errors in the experiments we developed a hardware software complex. The measurements were simultaneously gathered from multiple receivers located in the area with a radius smaller than the correlation radius of TEC variations. Based on the developed analytical model we showed that, at a constant SNR, the transionospheric channel capacity increases with an increase in the channel bandwidth, significantly exceeding the channel coherence bandwidth. It was found that the errors in measuring TEC limits the possibilities of spreading channel bandwidth and increasing capacity. Experimental studies showed that under the presence of errors, the gain after correction depends on the season of the year and was observed 2.5 … 7 times.
