A low-complexity KL expansion-based channel estimator for OFDM systems
(2005)This paper first proposes a computationally efficient pilot-aided linear minimum mean square error (MMSE) batch channel estimation algorithm for OFDM systems in unknown wireless fading channels. The proposed approach employs ... -
Low-Complexity MAP-Based Successive Data Detection for Coded OFDM Systems Over Highly Mobile Wireless Channels
(IEEE-INST Electrical Electronics Engineers Inc, 2011)This paper is concerned with the challenging and timely problem of data detection for coded orthogonal frequency-division multiplexing (OFDM) systems in the presence of frequency-selective and very rapidly time varying ... -
A low-complexity time-domain MMSE channel estimator for space-time/frequency block-coded OFDM systems
(Hindawi Publishing Corporation, 2006)Focusing on transmit diversity orthogonal frequency-division multiplexing (OFDM) transmission through frequency-selective channels this paper pursues a channel estimation approach in time domain for both space-frequency ... -
Lower lower-critical spin-glass dimension from quenched mixed-spatial-dimensional spin glasses
(Amer Physical Soc., 2018)By quenched-randomly mixing local units of different spatial dimensionalities we have studied Ising spin-glass systems on hierarchical lattices continuously in dimensionalities 1 <= d <= 3. The global phase diagram in ... -
LSB Image Steganography Based on Blocks Matrix Determinant Method
(KSII-KOR SOC Internet Information, 2019)Image steganography is one of the key types of steganography where a message to be sent is hidden inside the cover image. The most commonly used techniques for image steganography rely on LSB steganography. In this paper, ... -
Luleburgaz Train Station At The Turn Of The Twentieth Century
(Middle East Technical Univ, 2011)The literature on the architecture of the Ottoman railway buildings is highly limited. In terms of architectural history the data presented here gathered through original documents at archives and personal collections is ... -
Machine Learning Approaches for Predicting Protein Complex Similarity
(Mary Ann Liebert Inc Publ, 2017)Discriminating native-like structures from false positives with high accuracy is one of the biggest challenges in protein-protein docking. While there is an agreement on the existence of a relationship between various ... -
Machine learning model to predict an adult learner's decision to continue ESOL course
(Springer, 2019)This study investigated the ability of the demographic and the affective variables to predict the adult learners' decision to continue ESOL courser. 278 adult learners, enrolled on ESOL course at FLS institution in Istanbul, ... -
Macroeconomic adjustment in Asia after the global financial crisis: Japan, Korea, and China
(Nova Science Publishers, Inc., 2017)[Abstract Not Available] -
Macroeconomic and institutional determinants of financialisation of non-financial firms: Case study of Turkey
(Oxford University Press, 2014)We observe that industrial firms in Turkey have shifted substantial amounts of working capital from production activities to the purchase of high-yield interest-bearing assets most notably public bonds to ensure immediate ... -
The making of the 'new woman': narratives in the popular illustrated press from the Ottoman Empire to the new Republic (1890-1920s)
(Routledge Journals, 2019)The genre of social narrative was prominent in the printed press of the Ottoman Empire to the early Republic of Turkey (1850s-1920s). The ideological narratives disseminated through the periodical press were influential ... -
Making transnational publics: Circuits of censorship and technologies of publicity in Kurdish media circulation
(Wiley-Blackwell, 2013)Kurdish media producers who interweave social and political agendas with their filmmaking are often marginalized within Turkish media worlds. Impeded by national censorship these filmmakers move between national and ... -
Management Information Systems: The Virtual Team Scorecard (VTS)
(2013)Organizations resisting changes are missing opportunities to grow or to become or remain competitive. Management Information Systems (MIS) used as decision support systems may support organizations in making use of changes ... -
Managing Fuel Coal Supply Chains With Multiple Objectives and Multimode Transportation
(AMER SOC ENGINEERING MANAGEMENT, 2013)Power companies require sophisticated tools to manage fuel-coal supply chains which include multiple suppliers coal contracts and multimode transportation routes. In this article a multi-objective model which is integrated ... -
Managing natural gas demand for free consumers under uncertainty and limited storage capacity
(Elsevier, 2020)Demand for energy sources depends on several factors such as population growth, urbanization, industrialization, and climate. Among fundamental energy sources, natural gas is characterized by storage limitations and ... -
MAP channel-estimation-based PIC receiver for downlink MC-CDMA systems
(Hindawi Publishing Corporation, 2008)We propose a joint MAP channel estimation and data detection technique based on the expectation maximization (EM) method with paralel interference cancelation (PIC) for downlink multicarrier (MC) code division multiple ... -
Mapping the two-component atomic Fermi gas to the nuclear shell-model
(Springer, 2014)The physics of a two-component cold Fermi gas is now frequently addressed in laboratories. Usually this is done for large samples of tens to hundreds of thousands of particles. However it is now possible to produce few-body ... -
