  • Channel estimation for OFDM-IM systems 

    Acar, Yusuf; Aldırmaz Çolak, sultan; Başar, Ertuğrul (2019)
    Orthogonal frequency division multiplexing with index modulation (OFDM-IM) has been recently proposed to increase the spectral efficiency and improve the error performance of multicarrier communication systems. However, ...
  • Comparison of lung cancer detection algorithms 

    Günaydın, Özge; Günay, Melike; Şengel, Öznur (International Scientific Meeting on Electrical-Electronics and Biomedical Engineering and Computer Science (EBBT), 2019)
    Lung cancer is a kind of difficult to diagnose and dangerous cancer. It commonly causes death both men and women so fast accurate analysis of nodules is more important for treatment. Various methods have been used for ...
  • Cyclostationary analysis of respiratory signals with application of rate determination 

    Saatçi, Esra; Saatçi, Ertuğrul; Akan, Aydın (2019)
    Respiratory signals are periodic-like signals where the noisy periodic pattern repeats itself. Therefore, based on a stationarity assumption, autocorrelation function contains noisy cycles in time-lag with the same rate ...
  • High performance OFDM with index modulation 

    Acar, Yusuf; Cooklev, Todor (2019-02)
    Orthogonal frequency division multiplexing (OFDM) with index modulation (OFDM-IM), which has been recently proposed as an alternative waveform to classical OFDM, generally achieves lower bit error rate compared to classical ...
  • Incu-Stream 1.0: An Open-Hardware Live-Cell Imaging System Based on Inverted Bright-Field Microscopy and Automated Mechanical Scanning for Real-Time and Long-Term Imaging of Microplates in Incubator 

    GÜRKAN, GÜRAY; Gürkan, Koray (2019)
    Microplate (i.e. microwell plate) is a flat plate that has a specific number of wells to be used as small test tubes in cell-culture studies. In most of the low-budget mammalian cell study laboratories, highly skilled ...
  • Analysis of linear lung models based on state-space models 

    Saatçi, Esra; Saatçi, Ertuğrul; Akan, Aydın (Elsevier Ireland Ltd., 2020-01)
    Background and Objectives: Linear parametric respiratory system models have been used in the model-based analysis of the respiratory system. Although there are studies exploring the physiological correctness and fitting ...
  • Receiver Design for Dual-Mode Index Modulation Aided OFDM 

    Acar, Yusuf; Aldırmaz Çolak, Sultan (2019-04-12)
    Nowadays, variants of Spatial Modulation (SM) are studied by a lot of researchers in order to increase Spectral Efficiency (SE) more. One of the important variants of SM is known as Orthogonal Frequency Division Multiplexing ...
  • eal-Time Video Frame Differentiator Based on DDR3 SDRAM Memory Interface 

    Davutoğlu, Doğancan (2018-08)
    In this paper, design of a real-time video frame differentiator based on an external memory interface is proposed. Furthermore, implementation and simulation processes of the design is discussed. The proposed design is ...
  • Texture Analysis Based Iris Recognition 

    Gürkan, Güray; Akan, Aydın (2006-01)
    In this paper, we present a new method for personal identification, based on iris patterns. The method composed of iris image acquisition, image preprocessing, feature extraction and finally decision stages. Normalized ...
  • A novel EOG-based wireless rapid communication device for people with motor neuron diseases 

    Uşaklı, Ali Bülent; Gürkan, Serkan; Gürkan, Güray (Taylor and Francis Online, 2018-11-22)
    In this study, a new electrooculography (EOG) based system that provides efficient communication for people suffered from motor neuron diseases is presented. The system consists of two distinct devices. The first device ...
