Multidimensional index modulation for 5G and beyond wireless networks
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2021)
Index modulation (IM) provides a novel way for the transmission of additional data bits via the indices of the available transmit entities compared with classical communication schemes. This study examines the flexible ...
Characterization of LEDs for visible-light communications
(SPIE-Society of Photo-Optical Instrumentation Engineers, 2021)
Recent advances in solid-state technologies have enabled the development of light-emitting diodes (LEDs) with favorable features such as long life expectancy, low-power consumption, and reduced heat dissipation. Visible-light ...
Infinity shell shaped mimo antenna array for mm-wave 5g applications
(MDPI AG, 2021)
In this paper, a novel single layer Multiple Input–Multiple Output (MIMO) antenna for Fifth-Generation (5G) 28 GHz frequency band applications is proposed and investigated. The proposed MIMO antenna operates in the Ka-band, ...
Precoding based cross-tier interference mitigation in centralized-RAN
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2021)
This letter considers a two-tier downlink interference problem as a case of study, where macrocell user equipment (UE) shares the same frequency band with femtocell UE and suffers from severe cross-tier interference. Power ...
Detection, identification, and direction of arrival estimation of drone FHSS signals with uniform linear antenna array
(IEEE - Institute of Electrical and Electronics Engineers, Inc, 2021)
Safety, security, and privacy are three critical concerns affiliated with the use of drones in everyday life. Considering their ever-shrinking sizes and capabilities, being aware of drone activities in the vicinity becomes ...
Partial-beam non-orthogonal multiple access (PB-NOMA) with fuzzy clustering
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2021)
This letter proposes a partial-beam non-orthogonal multiple access (PB-NOMA) system for millimeter wave (mmWave) channels. In the proposed system, the user terminals (UT)s partially belong to different user groups and ...
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 ...
