In the paper, a method for the estimation of type I and type II errors of the built-in diagnostic hardware depending on the preventive maintenance periodicity is proposed. The approach considers an operational process of electronics as a Semi-Markov process with states of hazardous, latent and fictitious failures. The derived expressions may be used for the evaluation and analysis of the mentioned...
In the paper, operation algorithms of the N-OFDM modem for channels with the Additive White Gaussian Noise (AWGN) are considered. The algorithms are based on the Hartley transform under the optimal demodulation by the estimation of the received signals amplitudes using the Cauchy method. The experimental results for interference immunity estimation are provided for different values of spacing frequencies...
In the paper, a method of an optimal N-OFDM signals demodulator is considered. Signals are generated by means of the Hartley transform by the estimation of the received signals amplitudes using the Cauchy method. The experimental data outlined in the paper corresponds to the system interference immunity analysis for different values of spacing frequencies between subcarriers frequencies under the...
In the paper, mathematical support and software of a computer-aided design system of preventive maintenance schedule of radio communication equipment are proposed. Mathematical support is based on a Monte Carlo simulation model of an operational process that realizes multivariate approach of reliability indices estimation. System's software was implemented using C++ language and Matlab instruments...
The paper is devoted to the analysis of the strain impact on the reliability of optic-fiber communication lines. The reasons of strain appearance in optical fiber are discovered and two models, analytical and simulation, are proposed for the estimation of the integrated reliability indices of fiber-optic lines. The results, obtained by means of the models, can be used for the estimation of recommended...
