Adaptive windowing of insufficient CP for joint minimization of ISI and ACI beyond 5G
Peköz, Berker; Köse, Selçuk; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2017)Using minimum, even insufficient guards are proposed to achieve the spectral efficiency and latency requirements of cellular communication systems beyond 5G. This leads to interference in both time and frequency domains. ... -
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. ... -
Flexibility through hybrid waveforms
Peköz, Berker; Köse, Selçuk; Arslan, Hüseyin (Institution of Engineering and Technology, 2020)In search of a flexible waveform, this chapter starts by manipulating orthogonal frequency division multiplexing (OFDM) into being more flexible to further optimize time and frequency localization to facilitate a better ... -
Flexible radio access beyond 5G: A future projection on waveform, numerology, and frame design principles
Ankaralı, Zekeriyya Esat; Peköz, Berker; Arslan, Hüseyin (IEEE-Inst Electrical Electronics Engineers Inc, 2017)To address the vast variety of user requirements, applications, and channel conditions, flexibility support is strongly highlighted for 5G radio access technologies (RATs). For this purpose, usage of multiple orthogonal ... -
Innovative telecommunications training through flexible radio platforms
Demir, Ali Fatih; Peköz, Berker; Köse, Selçuk; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers, 2019)The everchanging telecommunication industry is in severe need of a highly skilled workforce to shape and deploy future generation communication systems. This article presents innovative telecommunication training that is ... -
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 ... -
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. ... -
Waveform design principles for 5G and beyond
Elkourdi, Mohamed H.; Peköz, Berker; Güvenkaya, Ertuǧrul; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2016)Various emerging applications in future wireless networks require rethinking the access techniques not only from the capacity perspective but also satisfying a wide variety of requirements under the same framework. Traditional ...
