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 ...
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. ...
Waveform-domain NOMA: The future of multiple access
(Institute of Electrical and Electronics Engineers Inc., 2020)
This paper introduces a novel non-orthogonal multiple access (NOMA) concept named waveform-domain NOMA, which proposes the coexistence of different waveforms in the same resource element (RE). Regarding the demands of each ...
Spectrum occupancy prediction exploiting time and frequency correlations through 2D-LSTM
(Institute of Electrical and Electronics Engineers Inc., 2020)
The identification of spectrum opportunities is a pivotal requirement for efficient spectrum utilization in cognitive radio systems. Spectrum prediction offers a convenient means for revealing such opportunities based on ...
A mobile parallel manipulator for the elbow rehabilitation of parkinsonian patients
(Institute of Electrical and Electronics Engineers Inc., 2020)
This study presents a two degrees of freedom (DoF) parallel manipulator that enables Parkinsonian Patients to regularly do the assigned rhythmic tasks in order to reduce the symptoms of motor disorders. Considering the ...
Non-orthogonal multiple access for terahertz communication networks
(Institute of Electrical and Electronics Engineers Inc., 2020)
Terahertz communications is one of the promising technologies for the future mobile communication networks. Due to the ever increasing need for high-speed data transfer, higher bandwidths are required. As a solution, higher ...
