Physical effect of in-phase and quadrature imbalance in delay-doppler domain
(Institute of Electrical and Electronics Engineers Inc., 2021)
Orthogonal time frequency space (OTFS) technique is a recent two-dimensional (2-D) modulation aiming to exploit both time and frequency selectivity of doubly dispersive wireless channel, which significantly affects the ...
Efficient spectral access in distributed cooperative cognitive radio networks
(Institute of Electrical and Electronics Engineers Inc., 2021)
The cognitive users (CUs) in the cooperative communication may serve as relay nodes for conveying the signal received from the primary users (PUs) to their destinations, provided that both the PUs and the CUs minimum rate ...
Sparse coding with enhanced atom selection for FDD massive MIMO channel estimation
(Institute of Electrical and Electronics Engineers Inc., 2021)
In sparse coding-based channel estimation, atom selection is based on jointly minimizing the sparsity and the error of the representation of the noisy measurement. However, this selection is not necessarily optimal in terms ...
Validity and reliability of the Turkish version of screening tool on distress in fertility treatment (SCREENIVF)
(NLM (Medline), 2021)
BACKGROUND: Women diagnosed with infertility and receiving infertility treatment reported high levels of depressive symptoms, anxiety and distress. Infertile women should first be screened for psychosocial risks. Psychosocial ...
Seismic performance of existing RC framed buildings using pushover analysis method
(Springer Science and Business Media Deutschland GmbH, 2021)
The aim of this study is to present a methodology on the determination of the seismic performance of existing reinforced concrete (RC) structures subjected to earthquake effects. This paper focuses on the assessment of ...
Phase index-based receive spatial modulation PHY security against supervised pattern recognition
(IEEE - Institute of Electrical and Electronics Engineers, Inc, 2021)
Receive Spatial Modulation (RSM) uses the index of the receive antenna to convey additional information bits, which reduces the receiver complexity and improves spectral efficiency. Additionally, it provides inherent ...
Improving connectivity via multi-user scheduling in 5G and beyond networks
(IEEE - Institute of Electrical and Electronics Engineers, Inc, 2021)
In this paper, a novel, yet efficient, multi-user scheduling scheme based on mode selection and power allocation is presented for 5G and beyond networks. The proposed scheme schedules the users in co-existence (CE) and non ...
Reconfigurable intelligent surface (RIS): Eigenvalue decomposition-based separate channel estimation
(Institute of Electrical and Electronics Engineers Inc., 2021)
Reconfigurable intelligent surface (RIS) has recently drawn significant attention in wireless communication technologies. However, identifying, modeling, and estimating the RIS channel in multiple-input multiple-output ...
Small object detection and tracking from aerial imagery
(Institute of Electrical and Electronics Engineers Inc., 2021)
Object detection and tracking from airborne imagery draws attention to the parallel development of UAV systems and computer vision technologies. Aerial imagery has its own unique challenges that differ from the training ...
Deep learning-based blind image super-resolution using iterative networks
(Institute of Electrical and Electronics Engineers Inc., 2021)
Deep learning-based single image super-resolution (SR) consistently shows superior performance compared to the traditional SR methods. However, most of these methods assume that the blur kernel used to generate the ...
