Theoretical analysis of the co-existence of LTE-A signals and design of an ML-SIC Receiver
(Institute of Electrical and Electronics Engineers, 2015)
The increasing number of mobile devices and the demand for large throughput requiring applications has hampered access to the limited frequency spectrum. The goal of this work is to introduce a new degree of freedom to the ...
A hybrid downlink NOMA with OFDM and OFDM-IM for beyond 5G wireless networks
(IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)
In this paper, a hybrid power domain non-orthogonal multiple accessing (NOMA) scheme by the superposition of orthogonal frequency division multiple accessing (OFDM) and index modulated OFDM (OFDM-IM) technologies is presented ...
Utilization of aerial heterogeneous cellular networks: Signal-to-interference ratio analysis
(Korean Institute of Communications and Information Sciences (K I C S), 2018)
As a component of future communication networks, aerial telecommunication platforms are a promising solution to meet surging traffic demands. These platforms can be used as aerial base stations (ABSs) to build an aerial ...
Mutual coupling compensation in receiving antenna arrays
(Applied Computational Electromagnetics Society (ACES), 2020)
Mutual coupling compensation in uniform linear and circular receiving antenna arrays of thin wire dipoles is presented. It was observed that the mutual impedance is independent of the incident angle and depends solely on ...
Physical layer authentication scheme in beamspace MIMO systems
(Institute of Electrical and Electronics Engineers Inc., 2022)
The broadcast nature of wireless communication makes it vulnerable to various security threats such as spoofing attacks. Physical layer (PL) authentication has emerged as a promising and powerful approach to secure future ...
Characterization of atmospheric absorption in the 60 GHz frequency band using a multi-pole material model
(Applied Computational Electromagnetics Society, 2019)
Atmospheric attenuation of electromagnetic signals at the 60 GHz frequency band is dominated by oxygen absorption which represents a major obstacle to 5G communications using this band. So far, only empirical equations ...
Mutual coupling compensation in receiving arrays and its implementation on software defined radios
(Applied Computational Electromagnetics Society, 2020)
Mutual coupling is compensated in a four element uniform linear receiving array using software defined radios. Direction of arrival (DoA) is estimated in real-time for the array with spacing d=lambda/4. The decoupling ...
Flexible guard structure for timing synchronization in coordinated networks
(Institute of Electrical and Electronics Engineers Inc., 2022)
In this letter, a novel and flexible hybrid guard duration (HGD) based on zero tail (ZT) and cyclic prefix (CP) concepts is proposed for facilitating timing synchronization (TS) in coordinated multi-point (COMP) networks. ...
New physical layer key generation dimensions: Subcarrier indices/positions-based key generation
(Institute of Electrical and Electronics Engineers Inc., 2021)
In this letter, novel algorithms for secret key generation from the wireless channel in multi-carrier systems are proposed for ensuring the confidentiality and authentication in wireless communication systems. The novelty ...
Ray tracing-based maritime channel analysis for millimeter radiowaves
(Springer, 2019)
In this work, we present and analyze the simulation results of millimeter-wave propagation channel performed over the sea surface for ship to ship scenario. We present a channel characterization study where channel parameters ...
