Enhancing physical layer security in AF relay-assisted multicarrier wireless transmission
(Wiley, 2018)
In this paper, we study the physical layer security problem in the dual-hop orthogonal frequency division multiplexing-based wireless communication system. First, we consider a single-user single-relay system and study a ...
Scattering from chiral cylinders of arbitrary cross-sections above a ground plane
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2021)
The main purpose of this work is to solve the problem of electromagnetic scattering from a chiral cylinder of arbitrary cross-section above an infinite perfect electric conducting (PEC) plane. Using image theory, this ...
High-gain pattern reconfigurable MIMO antenna array for wireless handheld terminals
(The Institute of Electrical and Electronics Engineers, 2016)
The analysis, design, experimental development, and test results of a high-gain pattern reconfigurable antenna array are presented. Unlike traditional phased arrays, the proposed array has a compressed footprint making it ...
Time-domain iterative multiregion technique for 3-D scattering and radiation problems
(Ieee-Inst Electrical Electronics Engineers Inc, 2016)
Integration of the finite-difference time-domain (FDTD) method into the iterative multiregion (IMR) technique, an iterative approach used to solve large-scale electromagnetic scattering and radiation problems, is presented ...
HM-net: A regression network for object center detection and tracking on wide area motion imagery
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2022)
Wide Area Motion Imagery (WAMI) yields high resolution images with a large number of extremely small objects. Target objects have large spatial displacements throughout consecutive frames. This nature of WAMI images makes ...
Enhancing the performance of low priority SUs using reserved channels in CRN
(IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)
Cognitive radio networks (CRNs) are considered a promising solution for spectrum resources scarcity and efficient channel utilization. In this letter, multi-dimensional analytical Markov model based on reservation channel ...
OFDM-subcarrier index selection for enhancing security and reliability of 5G URLLC services
(IEEE-Inst Electrical Electronics Engineering Inc., 2017)
An efficient physical layer security technique, referred to as OFDM with subcarrier index selection (OFDM-SIS), is proposed for safeguarding the transmission of OFDM-based waveforms against eavesdropping in 5G and beyond ...
Eight element side edged framed MIMO antenna array for future 5G smart phones
(MDPI, 2020)
This paper presents a novel design of a Multiple Input Multiple Output (MIMO) antenna system for next generation sub 6 GHz 5G and beyond mobile terminals. The proposed system is composed of a main board and two side boards. ...
Ultra-wideband pentagonal fractal antenna with stable radiation characteristics for microwave imaging applications
(MDPI, 2022)
For microwave imaging applications, a design for an ultra-wideband (UWB) fractal antenna is presented. The antenna design is composed of a pentagonal fractal patch radiator fed by a modified co-planar waveguide (CPW) ground ...
Generalized coordinated multipoint framework for 5G and beyond
(Institute of Electrical and Electronics Engineers Inc., 2021)
The characteristic feature of 5G and beyond networks is the diversity of services, which is required to support different user needs. However, the requirements for these services are often competing in nature, which impresses ...
