The paper is concentrated on mathematical modeling of an emitted signal transformation to the signal which is similar to a real received signal. The hardware implementation of the simulation model for radar systems allows us to produce signals for checking of real radar systems. The most challenging problem is to develop real time simulator which allows us to obtain signals reflected from terrains of different types where parameters of signal are changeable. The material of this paper shows how this problem can be solved for radar altimeter with chirp frequency modulation. The methods, simulator scheme, and some model results are presented in this paper.

Paper shows, that narrow band interference suppression given by correlation process is dependent on modulating sequence length and less on modulation type. Modulation type determines shape of I/Q-components and its spectrum form. Thus the comparative analysis for BOC(n) and MSK-BOC(n) types is given relying on the weakest narrow band interference suppression. When the modulating sequence length is the same, MSK-BOC's immunity is more than 2 dB better than BOC's.

In this paper, an electrodynamics analysis of the microwave material is performed, in order to lay its parameters in a program for the design of microwave devices. As the program used AWR Design Environment, which allows you to quickly and easily obtain the topologies of microspin devices. Obtaining the parameters of the substrate is carried out using a vector network analyzer, the R&S ZVA 24, two air-coaxial junctions and a program with a unique mathematical code. In order to verify the results obtained, a compact branch-line coupler was designed in the study of the material, which was then manufactured. The obtained results showed good convergence of the experimental and theoretical characteristics.

With the advent of digital transmission systems, the task of the discrete-time signal reconstruction became very important. Notice that the task of the discrete-time signals reconstruction is similar to the task of functions interpolation in numerical mathematics. In case of practical use of reconstruction methods one of the most important thing is to provide necessary accuracy of signal reconstruction. It depends both on type of the original analog signal and length of the discrete-time signal. This paper presents results of the research on the accuracy of the periodic discrete-time finite-length signal reconstruction by means of a Whittaker-Kotelnikov-Shannon interpolation formula. To estimate the accuracy of reconstruction the signal power to the error reconstruction power ratio has been employed. Two methods to increase the number of samples are considered. It is demonstrated that the formal increase in number of samples does not provide the of reconstruction error reduction every time. The conditions making reconstruction error on the dimensionless sampling rate ratio appear as the amount of the monotonic dependence with local extremums are defined. The ratio between the frequency of a signal, sampling rate and number of discrete samples providing minimum reconstruction error is determined.

Results of autodyne response formation features in the microwave oscillator stabilized by the external high-Q cavity are presented. An analysis is carried out for the case of strong reflected emission when the reflected wave amplitude is commensurable with the natural oscillation amplitude of the oscillator. The coupling between the main operation cavity and the stabilizing cavity is performed on the base of the band-elimination filter.

In this paper simultaneous transmission of five QAM-modulated mode channels in a single-core fiber with Kerr nonlinearity properties is investigated. It is shown analytically and by means of simulation that the presence of strong linear mode coupling leads to an increase of nonlinear impairments. In the weak-coupling regime the interaction result has a random nature and can also lead to an increase of nonlinear impairments. The distribution histogram of the difference between rms of nonlinear impairments in the case of presence and in the case of absence of linear mode coupling for the weak-coupling regime is obtained.

This article proposes an automated method for detection of cepstral markers of speech signals under psychogenic disorders based on the method of improved complete ensemble empirical mode decomposition with adaptive noise. The method consists in decomposition of a speech signal with the help of the improved complete ensemble empirical mode decomposition with adaptive noise into frequency components with the subsequent formation of a set of informative components (concentration of information on psychogenic disorders), and the determination of their cepstral markers. A block diagram for the developed method is presented. The research is conducted using the generated verified signal base of healthy male and female patients, and patients with psychogenic disorders, aged 18 to 60 years. It follows in accordance with the results of the study that the psychogenic disorders affect the vocalized characteristics of the vocal tract, and are sufficiently fully displayed in cepstral markers. The proposed automated method can be used in remote monitoring systems of psychogenic disorders, and introduced into clinical practice of a psychiatrist to accelerate the treatment process.
