Fading-aligned OFDM with index modulation for mMTC services
Memişoğlu, Ebubekir; Başar, Ertuğrul; Arslan, Hüseyin (Elsevier B.V., 2019)5th generation (5G) of wireless networking is coming with diverse use cases, such as enhanced-Mobile BroadBand (eMBB), Ultra Reliable and Low Latency Communications (URLLC), and massive Machine Type Communications (mMTC). ... -
Foreword
Arslan, Hüseyin; Başar, Ertuğrul (Institution of Engineering and Technology, 2020)The most critical difference of the fifth generation (5G) mobile communication technology compared to previous generations is its ability to support a wide variety of services. In other words, the 5G technology is all about ... -
Guard band reduction for 5G and beyond multiple numerologies
Memişoğlu, Ebubekir; Kihero, Abuu Bakari; Başar, Ertuğrul; Arslan, Hüseyin (IEEE, 2020)The existence of inter-numerology interference (INI) is a major drawback for the flexible multi-numerology frame structure proposed for the upcoming fifth generation New Radio (5G-NR). Insertion of a guard band (GB) between ... -

Tusha, Armed; Dogan Tusha, Seda; Althunibat, Saud; Başar, Ertuğrul; Qaraqe, Khalid; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2022)Design of simple transceiver architectures is inevitable in order to provide low computational complexity, low power consumption and affordable cost in beyond 5G (B5G) wireless systems, but it results in hardware impairments ... -
Index modulation-based flexible waveform design
Tusha, Seda; Tusha, Armed; Başar, Ertuğrul; Arslan, Hüseyin (Institution of Engineering and Technology, 2020)The service limitations of conventional orthogonal frequency division multiplexing (OFDM)-based technologies have motivated academia and industry to seek for new solutions in order to support the emerging services and use ... -
Inter-numerology interference in OFDM-IM systems
Doğan Tusha, Seda; Tusha, Armed; Başar, Ertuğrul; Althunibat, Saud; Qaraqe, Khalid; Arslan, Hüseyin (Wiley, 2021)In 5G and beyond communication systems, distinct numerologies can coexist to serve diverse requirements for users and applications. However, the inter-numerology interference (INI) is a main challenge that significantly ... -
Low complexity peak-to-average power ratio reduction in OFDM-IM
Memişoğlu, Ebubekir; Başar, Ertuğrul; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2018)Orthogonal frequency division multiplexing with index modulation (OFDM-IM) employs the indices of the active subcarriers for information transmission, as an alternative to conventional OFDM. It offers high spectral efficiency ... -
Multidimensional index modulation for 5G and beyond wireless networks
Doğan Tusha, Seda; Tusha, Armed; Başar, Ertuğrul; Arslan, Hüseyin (IEEE-Institute of Electrical and Electronics Engineers Inc, 2021)Index modulation (IM) provides a novel way for the transmission of additional data bits via the indices of the available transmit entities compared with classical communication schemes. This study examines the flexible ... -
