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 ... -
Data-Aided Autoregressive Sparse Channel Tracking for OFDM Systems
Buyuksar, Ayse Betul; Şenol, Habib; Erküçük, Serhat; Cirpan, Hakan Ali (IEEE, 2016)In order to meet future communication system requirements channel estimation over fast fading and frequency selective channels is crucial. In this paper Space Alternated Generalized Expectation Maximization Maximum a ... -
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 ... -

Performance Investigation of IEEE 802.11af Systems Under Realistic Channel Conditions
Macit, Mustafa Can; Şenol, Habib; Erküçük, Serhat (IEEE, 2015)As the analog TV broadcasting channels have become less frequently used in the last decade there has been a great interest in these frequency bands for the deployment of metropolitan local and personal area networks. Among ... -
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 ... -
Realistic Channel Estimation of IEEE 802.11af Systems in TV White Space
Başaran, Mehmet; Macit, Mustafa Can; Şenol, Habib; Erküçük, Serhat (Institute of Electrical and Electronics Engineers Inc., 2020)This work investigates the realistic performance of IEEE 802.11af systems released for the efficient spectrum utilization of TV white space (TVWS). These systems are operated over many contiguous or non-contiguous channels ...
