The parameter of the stable non-Gaussian noise sequence is modulated by the binary message sequence to achieve a secure communication system. The characteristic exponent ‘alpha’ of a stable non-Gaussian noise sequence carries the binary information. The receiver of the proposed random communication system demodulates…

Herein we propose a non-negative real parametric generalization of Baskakov operators and call them α-Baskakov operators.We show that α-Baskakov operators can be expressed in terms of divided differences.Then, we obtain the nth order derivative of α-Baskakov operators in order to obtain its new representation as power…

In this article, we develop a novel algorithm for Doppler acquisition in fast Fourier transform (FFT)-based Global Navigation Satellite System (GNSS) receivers. The Doppler estimation is carried out in FFT domain by finding the frequency shift which maximizes the energy of the correlation vector. Subsequently, energy…

He is shown that Prony modelling can be used to reduce the effect of in-band interference in frequency modulated continuous-wave (FMCW) channel data. Results of the modelling are examined by comparing average power delay profiles and Doppler spectra with those obtained from FFT processing.

This study is based on the comparison of the results with an analysis method recommended for the Peak-to-Average-Power-Ratio (PAPR) reduction methods. This is one of the most significant problems in the Multiple Input–Multiple Output-Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems. Of the methods applie…

A new method is given for the optimal design of bandlimited Nyquist-type signal shapes for data communications, which maximizes its energy in a given time interval. The method is based on the periodically nonuniform sampling (PNS) theory making use of the linear splines. The computation is straightforward, and the con…

In this paper, the problem of signal-to-noise ratio (SNR) estimation of noisy transient signals is considered. The SNR estimation is performed based on the average energy of the transient and noise signals. The performance of the SNR estimator is evaluated in terms of normalized mean square error and normalized bias.…

A survey of exposure to radio frequency (RF) electromagnetic fields has been carried out in the area around TV broadcast antennas. The RF electromagnetic fields out of the measurement points were calculated by the developed software, which has 3D screening unit, based on Fuzzy Logic. It takes quite a long time to meas…
