Effect of Inter-Block-Interference-Free Region on Compressed Sensing Based Channel Estimation in TDS-OFDM Systems 

Başaran, Mehmet; Erküçük, Serhat; Şenol, Habib; Cirpan, Hakan Ali (IEEE, 2016)
Time domain synchronous orthogonal frequency division multiplexing (TDS-OFDM) is the basis technology for digital television standard (DTV) employed in some countries thanks to its high spectral efficiency when compared ...

Joint Wavelet-Based Spectrum Sensing and FBMC Modulation for Cognitive mmWave Small Cell Networks 

Hosseini, Haleh; Anpalagan, Alagan; Raahemifar, Kaamran; Erküçük, Serhat; Habib, Salman (Inst Engineering Technology-IET, 2016)
Millimetre-wave (mmWave) 5G communications is an emerging technology to enhance the capacity of existing systems by thousand-fold improvement. Heterogeneous networks employing densely distributed small cells can optimise ...

Hybrid MEMS-based Molecular Communication System 

Zeshan, Arooba; Baykas, Tuncer; Pusane, Ali Emre; Erküçük, Serhat (IEEE, 2019)
In this paper, we consider a molecular communication link integrated in a micro-electro mechanical system (MEMS) based environment. We apply acoustic tweezing techniques to the molecular communication system to increase ...

A New Approach for Coexistence of IEEE 802.11af and IEEE 802.22 Systems 

Ülgen, Oğuz; Baykas, Tuncer; Erküçük, Serhat (2018)
In this paper, various algorithms are proposed to help IEEE 802.11af and IEEE 802.22 wireless systems to coexist in TV white space by considering multiple techniques. By using busy tone, power control and multihop communication ...

Bayesian Compressive Sensing For Primary User Detection 

Başaran, Mehmet; Erküçük, Serhat; Cirpan, Hakan Ali (Inst Engineering Technology-IET, 2016)
In compressive sensing (CS)-based spectrum sensing literature most studies consider accurate reconstruction of the primary user signal rather than detection of the signal. Furthermore possible absence of the signal is not ...

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 ...

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 ...

Busy Tone Based Power Control for Coordination of IFFY 802.11af and 802.22 System 

Ülgen, Oğuz; Erküçük, Serhat; Karatalay, Onur; Baykas, Tuncer (IEEE, 2017)
In this paper, a new power control algorithm based on busy tone approach has been proposed for the coordination of IEEE 802.22 and IEEE 802.11af systems in TV white space. Different from the earlier studies, in addition ...

Busy tone based coexistence algorithm for WRAN and WLAN systems in TV white space 

Karatalay, Onur; Erküçük, Serhat; Baykaş, Tunçer (Inst Engineering Technology-IET, 2018)
TV White Space (TVWS) refers to frequency band reserved only for licensed terrestrial TV broadcasting and is opened to unlicensed use under regulatory conditions. While regulations protect licensed systems from interference ...

Channel Estimation for TDS-OFDM Systems in Rapidly Time-Varying Mobile Channels 

Başaran, Mehmet; Şenol, Habib; Erküçük, Serhat; Çırpan, Hakan Ali (IEEE-Inst Electrical Electronics Engineers Inc, 2018)
This paper explores the performance of time-domain synchronous orthogonal frequency-division multiplexing (TDS-OFDM) systems operated under rapidly time-varying mobile channels. Since a rapidly time-varying channel contains ...
