Cognitive security of wireless communication systems in the physical layer
Yılmaz, Mustafa Harun; Güvenkaya, Ertuğrul; Furqan, Haji Muhammed; Köse, Selçuk; Arslan, Hüseyin (Wiley-Hindawi, 2017)While the wireless communication systems provide the means of connectivity nearly everywhere and all the time, communication security requires more attention. Even though current efforts provide solutions to specific ... -
Extensionless adaptive transmitter and receiver windowing of beyond 5G frames
Peköz, Berker; Köse, Selçuk; Arslan, Hüseyin (IEEE - Institute of Electrical and Electronics Engineers, Inc, 2020)Newer cellular communication generations are planned to allow asynchronous transmission of multiple numerologies (waveforms with different parameters) in adjacent bands, creating unavoidable adjacent channel interference. ... -

Non-redundant OFDM receiver windowing for 5G frames and beyond
Peköz, Berker; Ankaralı, Zekeriyya Esat; Köse, Selçuk; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers (IEEE), 2020)Contemporary receiver windowed-orthogonal frequency division multiplexing (RW-OFDM) algorithms have limited adjacent channel interference (ACI) rejection capability under high delay spread and small fast Fourier transformation ... -
Partially overlapping filtered multitone with reconfigurable antennas in uncoordinated networks
Yılmaz, Mustafa Harun; Köse, Selçuk; Chamok, Nowrin H.; Ali, Mohammod; Arslan, Hüseyin (Elsevier Sciences Bv, 2017)Partially overlapping tones (POT) have recently been offered as a promising solution with the aim of decreasing the interference induced on the users for uncoordinated networks. Since each user causes interference on other ... -
Reducing precoder/channel mismatch and enhancing secrecy in practical MIMO systems using artificial signals
Peköz, Berker; Hafez, Mohammed; Köse, Selçuk; Arslan, Hüseyin (IEEE - Institute of Electrical and Electronics Engineers, Inc, 2020)Practical multiple-input-multiple-output (MIMO) systems depend on a predefined set of precoders to provide spatial multiplexing gain. This limitation on the flexibility of the precoders affects the overall performance. ...
