The paper is dedicated to solution the problem related to the practical implementation of a radio engineering data transmission system which is based on the theory of resolution time, in which amplitude-phase shift signals with N discrete signals are used. In this work, analytical expressions are obtained that allow taking into account the instability of the initial phase of the carrier of information signal when choosing a configuration of signal constellation. Block diagram for considered type ReDTS is presented. The selection data transmission algorithm is presented.

To the Matter of Implementation of Radio Engineering Data Transmission System with APSK-N-signal based on the Theory of Resolution Time

THE SOLUTION of the spectral problem is considered for a singular bundle of matrices A + λB of complete columnar rank. A method of calculating the eigenvalues of the regular kernel of the bundle is presented, which does not require its preliminary extraction, and also a method of calculating the corresponding linearly independent eigenvalues.

Solution of the spectral problem for a singular bundle of matrices

A new method of interpolation/approximation of univariate functions using exponential polynomials, both complete and reduced, generally using complex polynomials, was suggested. The solution is based on the Z-transformation of one variable function, predetermined by a discrete set of equally spaced samples. For the first time, the problem was solved for dynamic systems with proper frequencies of any multiplicity. The method of transition from time functions to full, and shortened operator models of selective radioelectronic devices was represented. In addition, the transfer ratio, reduced by Z-transform, corresponds exactly to the basic approximation in the modified method of the truncated operator equations. Based on some examples including IFA of ninth order (with three poles, each of which having multiplicity factor three) on exposure to complex FM/PM input signal, the usage possibility of precise as well as shortened exponential and operator polynomials aimed to design radioelectronic systems which are sensitive to phase variation during the transition process, was proved.

Z-Transform Exponential Approximation of One-Dimensional Functions: Theory and Applications

The article presents a specialized program for modeling well-known, including chaotic radio pulse processes, additive white and non-Gaussian noise, communications with multipath propagation of a signal, as well as classical signal processing algorithms in mobile communication systems, within the framework of the problem of detecting a signal in one-dimensional form, based on the MatLab language and taking into account the disadvantages inherent in both visual modeling tools and programming language. The modeling tools themselves, available in the future, will allow implementing a multidimensional signal processing option. 

Analysing the Classical Signal Detection In Channels With Complex Interference-Noise Environment

The singular spectral variant of exponential approximation is developed, which combines the order reduction of a polynomial by the singular method of the matrix beams on the first stage and recovering of the exponential polynomial of reduced order by the method of z-approximation on the second stage. Examples of this method application are presented typical for the circuit theory and radio electronics. In particular, the approximation of Bessel functions with accuracy ∝ 10–12 ••• 10–11is performed on the interval (0, 100π) by exponential polynomial of 28th order; the nine-stage amplifier order by sequential application of the methods of abbreviated operator equations and matrix beams is reduced three times with the absolute error of AFC approximation less than 3.10−3; the identification problem of sequence parameters for radar pulses is solved at signal/noise ratio in the range from 30 to 0 dB. Other possible areas of this method application are considered.
