Extended reduced-rank joint estimation of direction of arrival with mutual coupling for coherent signals
(Wiley Blackwell, 2019)
This paper proposes an extended method for direction-of-arrival (DOA) estimation with unknown mutual coupling for coherent signals. The proposed method employs the forward/backward spatial smoothing to decorrelate the ...
A spatially adaptive antenna array for mm-wave wireless channel control with microfluidics based reconfiguration
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)
Spatially adaptive antenna array (SAA) is an electronically scanned antenna array with capability of changing its physical location. This new capability allows SAA to control the wireless channel environment to increase ...
Radar-aided communication scheduling algorithm for 5G and beyond networks
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2022)
Radar and communication coexistence is an upcoming technology with numerous research opportunities in the medium access control (MAC) layer, particularly in scheduling and radio resource management (RRM). More efficient ...
OFDM with hybrid number and index modulation
(IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)
A novel transmission scheme is introduced for efficient data transmission by conveying additional information bits through jointly changing the index and number of active subcarriers within each orthogonal frequency division ...
User pairing and power allocation strategies for 3D VLC-NOMA systems
(Institute of Electrical and Electronics Engineers Inc., 2020)
In this letter, we propose two novel, yet efficient, user pairing schemes for non-orthogonal multiple access (NOMA) in 3D visible light communication (VLC). Our analysis is carried out assuming different heights for the ...
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 ...
Thresholds optimization for one-bit feedback multi-user scheduling
(Institute of Electrical and Electronics Engineers Inc., 2018)
We propose a new one-bit feedback scheme with scheduling decision based on the maximum expected weighted rate. We show the concavity of the 2-user case and provide the optimal solution which achieves the maximum weighted ...
DFT-based multi-directions directional modulation
(Institute of Electrical and Electronics Engineers, 2019)
In this letter, a physically secure multi-directions directional modulation scheme is proposed. The scheme provides an adaptive beam-width assignment, where each user is granted a different beam width based on its channel ...
Predicting path loss distribution of an area from satellite ımages using deep learning
(IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)
Path loss prediction is essential for network planning in any wireless communication system. For cellular networks, it is usually achieved through extensive received signal power measurements in the target area. When the ...
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 ...
