Detection of interdependent primary systems using wideband cognitive radios 

Yılmaz, Burak; Erküçük, Serhat (Elsevier GMBH Urban & Fischer Verlag, 2013)
Cognitive radios (CRs) may be sharing multiple frequency bands with primary systems if the CR is a wideband or an ultra wideband (UWB) system. In that case the CR should ensure all the coexisting primary systems in these ...

Flexible Physical Layer based Resource Allocation for Machine Type Communications Towards 6G 

Sadi, Yalçın; Erküçük, Serhat; Panayırcı, Erdal (IEEE, 2020)
The exponential growth of Internet of Things applications necessitates the design of next generation cellular systems to provide native support for machine type communications (MTC). While 5G aims at providing this native ...

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 ultra-wideband channel estimation: algorithm and performance analysis 

Özgör, Mehmet; Erküçük, Serhat; Çırpan, Hakan Ali (Springer, 2015)
Due to the sparse structure of ultra-wideband (UWB) channels compressive sensing (CS) is suitable for UWB channel estimation. Among various implementations of CS the inclusion of Bayesian framework has shown potential to ...
