Iterative near maximum-likelihood sequence detection for MIMO optical wireless systems
(IEEE, 2010-04)A major performance-limiting factor in terrestrial optical wireless (OW) systems is turbulence-induced fading. Exploiting the additional degrees of freedom in the spatial dimension, multiple laser transmitters combined ... -
Iterative signal detection under timing errors for optical wireless links with high mobility
(IEEE, 2021-11-01)In this paper, the problem of timing error for freespace optical links with high mobility is investigated. In particular, we consider a real scenario in which the sampling clock offset is randomly changing and, in addition, ... -
İşbirlikli haberleşmede birleştirilmiş zaman kayması ve sönümlemeli kanal katsayısı kestirimi
(IEEE, 2013)In this paper, we investigate joint channel gain and time offset estimation for two different data aided methods in cooperative communication with amplify-and-forward (AF) relaying. First one is the Cascaded Estimation ... -
Jet and underlying event properties as a function of charged-particle multiplicity in proton–proton collisions at TeX
(Springer Science+Business Media, 2013-12)Characteristics of multi-particle production in proton-proton collisions at root s = 7 TeV are studied as a function of the charged-particle multiplicity, N (ch). The produced particles are separated into two classes: those ... -
Jet energy scale and resolution in the CMS experiment in pp collisions at 8 TeV
(IOP , 2017)Improved jet energy scale corrections, based on a data sample corresponding to an integrated luminosity of 19.7 fb-1 collected by the CMS experiment in proton-proton collisions at a center-of-mass energy of 8 TeV, are ... -
Jet shapes of isolated photon-tagged jets in Pb-Pb and pp collisions at √sNN = 5.02 TeV
(American Physical Society, 2019-04-17)The modification of jet shapes in Pb-Pb collisions, relative to those in pp collisions, is studied for jets associated with an isolated photon. The data were collected with the CMS detector at the LHC at a nucleon- nucleon ... -
Joint bit and power loading for adaptive MIMO OFDM VLC systems
(Wiley, 2020-07)Visible light communication (VLC) is a short-range wireless access technology based on the dual use of illumination structure. The frequency-selective characteristics of VLC channels motivate the use of orthogonal frequency ... -
Joint frequency allocation and power control for minimum downlink interference in femtocellular networks
(2013-01)Due to the fact that the most of data services and more than half of calls are requested indoors, it has been dramatically important and even a must for cellular operators to provide more than adequate indoor coverage. ... -
Joint lifetime-outage optimization in relay-enabled IoT networks—A deep reinforcement learning approach
(IEEE, 2023-01)Network lifetime maximization in Internet of things (IoT) is of paramount importance to ensure uninterrupted data transmission and reduce the frequency of battery replacement. This letter deals with the joint lifetime-outage ... -
Joint modeling of histone modifications in 3D genome shape through Hi-C interaction graph
(Springer, 2021)Chromosome conformation capture experiments such as Hi-C are used to map the three-dimensional spatial organization of genomes. Even though Hi-C interactions are not biased towards any of the histone modifications, previous ... -
Joint or decoupled optimization: Multi-UAV path planning for search and rescue
(Elsevier, 2023-01-01)In this paper, we focus on path planning of drone teams deployed for search and rescue missions. The goal of the mission is to detect a target, inform the rescue personnel at the ground base station (BS), and form a ... -
A journey towards fully immersive media access
(2019)Universal media access (UMA) as proposed almost two decades ago is now reality. We can generate, distribute, share, and consume any media content, anywhere, anytime, and with/on any device. A technical breakthrough was the ... -
JQSRT impact factor and Elsevier Benedict and Poynting Awards
(Elsevier, 2012-11)We are very pleased to inform the JQSRT readers and authors of several important recent developments about the Journal. First of all, according to the ISI Journal Citation Reports database, the 2011 Impact Factor for JQSRT ... -
Kamera ve ataletsel ölçüm birimi iç kalibrasyonu
(IEEE, 2013)In this paper, we address the problem of internal calibration of a camera and an inertial measurement unit (IMU). The internal calibration of a camera and an IMU requires the determination of the relative orientation and ... -
Kaskat nakagami kanallara sahip röleli sistemler için dağıtılmış uzay-zaman kafes kod tasarımı
(IEEE, 2010)Bu çalışmada, tek roleli, işbirlikli ve kodlamalı bir sistemin kanallarının kaskat Nakagami dağılımlı olması durumundaki hata performans analizi yapılmıştır. Sistemin genel çiftsel hata olasılığı üst sınırı kullanılarak ... -
Kerr–Newman black holes can be generically overspun
(Springer Nature, 2019-04-08)We construct thought experiments involving the perturbations of Kerr-Newman black holes by neutral test fields to evaluate the validity of the weak form of the cosmic censorship conjecture. We first show that neglecting ... -
A knowledge driven policy framework for internet of things
(ScitePress, 2017)With the proliferation of technology, connected and interconnected devices (henceforth referred to as IoT) are fast becoming a viable option to automate the day-to-day interactions of users with their environment—be it ... -
Kombi̇natoryal test tekni̇kleri̇ni̇n karmaşık olay i̇şleme motorlarında uygulanması
(IEEE, 2012)Testing practice has a critical place during the design, implementation and integration of software, hardware and complex systems composed of these. Cost of failures caused by bugs that could not be detected and fixed early ... -
Konuşmacı aradeğerlemeli SMM tabanlı metinden konuşma sentezleme si̇stemi
(IEEE, 2011)Hidden Markov Model (HMM) based text-to-speech (TTS) systems offer many advantages compared to the concatenative approach. One of those advantages is the ability to interpolate between different speakers to generate new ... -
Kuvvetlendir-ve-aktar tipi işbirlikli haberleşme sistemlerinde zaman senkronizasyonu
(IEEE, 2010)The synchronization problem in wireless communication systems becomes more important especially in cooperative communication systems than it is for other diversity systems because all terminals in the cooperation use their ...
