Performance of Combinational Cooperative Detection Method under Realistic Conditions
Samo, Rameez Ahmed; Başaran, Mehmet; Erküçük, Serhat (IEEE Computer Society, 2020)Combinational cooperative detection (CCD) is a method where signal energies from multiple secondary users (SUs) are gathered in different combinations in order to reach a unique decision for each secondary user regarding ... -
Performance of IEEE 802.15.4a Systems in the Presence of Narrowband Interference
Fındıklı, Çağlar; Erküçük, Serhat; Çelebi, Mehmet Ertuğrul (IEEE, 2011)The regulatory agencies in Europe and Japan require the implementation of avoidance techniques in some bands to reduce interference to licensed systems. Accordingly ultra-wideband impulse radio (UWB-IR) based Wireless ... -
Physical-layer security in visible light communications
Yeşilkaya, Anıl; Çoğalan, Tezcan; Erküçük, Serhat; Şadi, Yalçın; Panayırcı, Erdal; Haas, Harald; Poor, Harold Vincent (Institute of Electrical and Electronics Engineers Inc., 2020)Optical wireless communications (OWC) and its potential to solve physical layer security (PLS) issues are becoming important research areas in 6G communications systems. In this paper, an overview of PLS in visible light ... -
Practical Implementation of the Combinational Cooperative Detection Method
Çatak, Evren; Erküçük, Serhat (Springer, 2015)In conventional cooperative detection a fusion center decides on the presence or the absence of a primary user (PU) by gathering all the information from secondary users (SUs) and conveys this decision to all users. This ... -
Primary User Detection in IEEE 802.15.4a Based Wireless Sensor Networks
Sabucu, Yağmur; Erküçük, Serhat (IEEE, 2013)Ultra wideband impulse radio (UWB-IR) technology has been defined in the IEEE 802.15.4a standard for location and ranging applications. In this paper UWB-IR sensors are considered in wireless sensor networks (WSNs) with ... -
Rapidly Varying Sparse Channel Tracking with Hybrid Kalman-OMP Algorithm
Büyükşar, Ayşe Betül; Şenol, Habib; Erküçük, Serhat; Cirpan, Hakan Ali (Springer, 2019)It is expected from future communication standards that channel estimation algorithms should be able to operate over very fast varying frequency selective channel models. Therefore in this study autoregressive (AR) modeled ... -
Sparse Code Multiple Access-Based Edge Computing for IoT Systems
Alnoman, Ali; Erküçük, Serhat; Anpalagan, Alagan (IEEE-Inst Electrical Electronics Engineers Inc, 2019)In this paper, a sparse code multiple access (SCMA)-based edge computing scheme is proposed for Internet-of- Things (IoT) systems. The aim of implementing SCMA, which is a nonorthogonal multiple access resource allocation ... -
Wavelet-based cognitive SCMA system for mmWave 5G communication networks
Hosseini, Haleh; Anpalagan, Alagan; Raahemifar, Kaamran; Erküçük, Serhat (Inst Engineering Technology-IET, 2017)Fifth generation (5G) communication networks can achieve high spectral efficiency using sparse code multiple access (SCMA) scheme when large number of users are trying to transmit their data simultaneously. The sparsity ...
