OFDM-subcarrier power modulation with two dimensional signal constellations
(2019 Innovations in Intelligent Systems and Applications Conference (ASYU), 2019)
An original modulation technique has been recently proposed for wireless communication systems known as OFDM- SPM (OFDM with Subcarrier Power Modulation). This technique utilizes a characteristic of the subcarriers of the ...
Improving the physical layer security of IoT-5G systems
(Springer, 2019)
Ensuring the security of the Internet of Things (IoT) is deemed as one of the most critical challenges and needs that have to be addressed in order to guarantee the successful deployment of IoT in emerging technologies ...
Security in UAV/Drone communications
(CRC Press, 2019)
This chapter highlights the latest advances and state-of-the-art research attempts performed towards applying physical layer security (PLS) to unmanned aerial vehicle (UAV) communication systems. It discusses some of the ...
Non-planar drive-sense coil structure for inductive MEMS microphones
(International Symposium on Advanced Engineering Technologies, 2019)
MEMS technology offers major advantages for the development of microphones including a small footprint, low power consumption, high sound sensitivity and bandwidth. Capacitive, piezoelectric, and inductive microphones have ...
Physical layer security for NOMA: requirements, merits, challenges, and recommendations
(2019)
Non-orthogonal multiple access (NOMA) has been
recognized as one of the most significant enabling technologies
for future wireless systems due to its eminent spectral efficiency,
its ability to provide an additional ...
Classifications and applications of physical layer security techniques for confidentiality: a comprehensive survey
(IEEE, 2019)
Physical layer security (PLS) has emerged as a new
concept and powerful alternative that can complement and may
even replace encryption-based approaches, which entail many
hurdles and practical problems for future ...
Multifunctional magnetic nanocarrier: synthesis, characterization and pH-responsive doxorubicin release profile
(2019)
In this study, carboxymethyl cellulose (CMC) functionalized superparamagnetic iron oxide nanoparticles (SPIONs) have been synthesized as a novel theranostic platform which enables magnetic resonance (MR) imaging-guided and ...
Cr: Colquiriite Lasers: Current Status and Challenges for Further Progress
(Progress in Quantum Electronics, 2019)
Cr: Colquiriite laser materials (Cr:LiCAF, Cr:LiSAF, Cr:LiSGaF) own broad absorption bands in the visible region that allow direct-diode pumping by well-developed low-cost red diodes. Moreover, they possess broad emission ...
A micro-scale biosensor for the detection of bacillus stearothermophilus spore germination
(International Conference on Engineering Technologies (ICENTE'19), 2019)
Germination of Bacillus Stearothermophilus bacterial spores is being used as a marker in sterilization monitoring systems to verify the success of sterilization processes in healthcare facilities. Such systems mainly employ ...
Optimization of hydrothermal synthesis of Ce3+ co-doped NaYF4, Yb3+, Er3+upconversion nanoparticles and investigation of their size, morphology, and phase transitions.
(ICENS, 2019)
In this study, the synthesis of water-soluble polyethyleneimine (PEI) modified UCNPs which were prepared by a hydrothermal method have been reported. The resultant UCNPs were small size and hexagonal β-phase structure ...
