Measurement based statistical channel characterization of air-to-ground path loss model at 446MHz for narrow-band signals in low altitude UAVs
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)
Powered by the advances in microelectronics technologies, unmanned aerial vehicles (UAVs) provide a vast variety of services ranging from surveillance to delivery in both military and civilian domains. It is clear that a ...
On the inherent physical-layer security of receive spatial modulation systems
(Institute of Electrical and Electronics Engineers Inc., 2020)
This paper investigates the physical-layer security attained by Receive Spatial Modulation (RSM) scheme against potential eavesdroppers. The impact of the involved parameters on the bit error rate (BER) at the legitimate ...
Orthogonal frequency division multiplexing with subcarrier gap modulation
(Institute of Electrical and Electronics Engineers Inc., 2020)
A new modulation scheme called orthogonal frequency division multiplexing with subcarrier gap modulation (OFDM-SGM) is proposed. The proposed scheme embeds extra information bits by exploiting the gap between the active ...
Design and implementation of an X-band passive RFID tag
(Institute of Electrical and Electronics Engineers Inc., 2020)
This paper presents a novel fully integrated energy harvester, multi-stage RF-DC rectifier, mode selector, RC oscillator, LC oscillator, and X-band power amplifier implemented in IBM 0.18-µm RF CMOS technology. We investigated ...
Leaching of iron and chromium from an indigenous ferro chromium alloy via a rotary evaporator: Optimum conditions determination and kinetic analysis
(Elsevier, 2020)
In the leaching process of chromium-containing precursor hexavalent chromium may form, which provokes damages to environment and human health. As a solution, leaching the chromium containing precursor with sulphuric acid ...
Joint overlap ratios and power allocation with user fairness in partial non-orthogonal multiple access (P-NOMA)
(Institute of Electrical and Electronics Engineers Inc., 2020)
In power-domain non-orthogonal multiple access (NOMA), since many users are able to utilize a single frequency subcarrier with different power levels, user interference occurs if successive interference cancellation (SIC) ...
Learned vs. hand-crafted features for deep learning based aperiodic laboratory earthquake time-prediction
(Institute of Electrical and Electronics Engineers Inc., 2020)
Earthquakes cause the deadliest and most costly disasters among all natural hazards. Geophysicists and data scientists have spent a lot of effort, trying to predict earthquakes time, location or magnitude to minimize these ...
Deep learning-assisted detection of PUE and jamming attacks in cognitive radio systems
(Institute of Electrical and Electronics Engineers Inc., 2020)
Cognitive radio (CR)-based internet of things systems can be considered as an efficient solution for futuristic smart technologies. However, CRs are naturally vulnerable to two major security threats; primary user emulation ...
Compressed sensing structured illumination microscopy
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)
We propose a new framework for super-resolution structured illumination microscopy (SR-SIM) based on compressed sensing (CS). Our framework addresses several key problems in SIM, including long readout time and photobleaching. ...
Towards zero waste in construction: A case study using green building certification systems
(Dicle University, 2020)
In many countries of the world like Turkey there are extensive civil engineering constructions in the forms of buildings, skyscrapers, dams, bridges, canals, culverts, pipes and roads. Each one of these activities lead to ...
