Development of Ag-Doped ZnO Thin Films and Thermoluminescence (TLD) Characteristics for Radiation Technology

open access: yesNanomaterials, 2022
This work examined the thermoluminescence dosimetry characteristics of Ag-doped ZnO thin films. The hydrothermal method was employed to synthesize Ag-doped ZnO thin films with variant molarity of Ag (0, 0.5, 1.0, 3.0, and 5.0 mol%).

OFDM comparison with FFT and DWT processing for DVB-T2 wireless channels

open access: yesInge-Cuc, 2018
Introduction: Recent studies on the FFT processing (Fast Fourier Transform) or DWT (Discrete Wavelet Transform) of the OFDM signal (Orthogonal Frequency Division Multiplexing) have shown pros and cons for DVB-T2 (Digital Video Broadcasting-Second ...

Statistical properties for multipath-relayed communications over fading channels [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2008
In this paper, a multipath transmission with no regenerative relays over fading channels has been addressed. The probability density function of minimum amplitude at relay stations input has been determined.

On the detection of a solar radio burst event that occurred on 28 August 2022 and its effect on GNSS signals as observed by ionospheric scintillation monitors distributed over the American sector

open access: yesJournal of Space Weather and Space Climate, 2023
As part of an effort to observe and study ionospheric disturbances and their effects on radio signals used by Global Navigation Satellite Systems (GNSS), alternative low-cost GNSS-based ionospheric scintillation and total electron content (TEC) monitors ...

Modeling of linear fading memory systems [PDF]

open access: yes, 1996
Motivated by questions of approximate modeling and identification, we consider various classes of linear time-varying bounded-input-bounded output (BIBO) stable fading memory systems and the characterizations are proved.

A novel-iterative simulation method for performance analysis of non-coherent FSK/ASK systems over Rice/Rayleigh channels using the wolfram language [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2016
In this paper, a new approach in solving and analysing the performances of the digital telecommunication non-coherent FSK/ASK system in the presence of noise is derived, by using a computer algebra system.
