Beam squint inspired multiple access technique in massive MIMO systems
(Institute of Electrical and Electronics Engineers Inc., 2022)
Massive multiple-input multiple-output (mMIMO) systems implementing wideband signaling have been found to suffer from beam squinting problem. In multicarrier systems, beam squint causes spreading of the beam to multiple ...
On emulating and controlling rician propagation in wireless laboratory
(Institute of Electrical and Electronics Engineers Inc., 2022)
Channel emulators are usually used to evaluate preliminary performances of the newly developed wireless algorithms in the laboratory without resorting to the on-site measurements which are generally complex and costly. In ...
Control of fractional delay effect for SC transmission in beyond 5G networks
(Institute of Electrical and Electronics Engineers Inc., 2022)
Wireless networks beyond 5G are expected to support a wide range of applications and use cases, and single-carrier (SC) based wireless technologies have been considered in the literature as a suitable solution for ...
Beam squint effect in multi-beam mmWave massive MIMO systems
(Institute of Electrical and Electronics Engineers Inc., 2022)
In multicarrier wideband millimeter-wave (mmWave) communications, as the size of antenna array increases, as in massive multiple-input multiple-output (MIMO), an additional propagation delay of the electromagnetic wave at ...
The impact of varicocele repairon conventional semen paramaeters in infertile men: A meta-analysis using pre- and post-operative data.
(Elsevier Science Inc., 2022)
Objective Varicocele is a widespread disorder affecting about 15% of the normal male population, 25% of men with abnormal semen analysis, and 35-40% of primary infertile men. There are few systematic reviews and meta-analyses ...
Effect of varicocele repair on conventional sperm parameters in infertile patients with clinical varicocele: A systematic review and metaanalysis.
(Elsevier Science Inc., 2022)
Objective Varicocele is present in almost 35-40% of men presenting with primary infertility. Despite the significant role of varicocele in the pathogenesis of male infertility, the impact of varicocele repair (VR) on ...
Physician and patient preferences for oral anticoagulation therapy decision-making in atrial fibrillation: Results from a national best-worst scaling survey in Turkey (PREF-AF)
(Elsevier Science Inc., 2022)
Objectives Cost-utility modeling informs reimbursement decisions and is based on the premise that health outcome improvements can be expressed as disease-independent utility scores. Previous cost-utility analyses of ...
Predicting path loss distributions of a wireless communication system for multiple base station altitudes from satellite images
(IEEE Computer Society, 2022)
It is expected that unmanned aerial vehicles (UAVs) will play a vital role in future communication systems. Optimum positioning of UAVs, serving as base stations, can be done through extensive field measurements or ray ...
Iterative kernel reconstruction for deep learning-based blind image super-resolution
(IEEE Computer Society, 2022)
Deep learning based methods have received a great deal of interest in recent years to solve the single image superresolution (SISR) problem and their performance is proven to be superior when compared to classical SR ...
Exploiting OTFS frame structure for PAPR reduction
(Institute of Electrical and Electronics Engineers Inc., 2022)
Wireless technologies have always been the cornerstone of industrial progress. However, as industrial technologies have improved and advanced services have emerged, the demands of industry have meant that wireless technologies ...
