Error performance enhancement and complexity reduction in OFDM systems via coordinate interleaving under practical impairments
Reşat, Mustafa Anıl; Tusha, Armed; Doğan Tusha, Seda; Özyurt, Serdar; Arslan, Hüseyin (Turkiye Klinikleri, 2024)In this work, subcarrier coordinate interleaving (CI) is implemented to orthogonal frequency division multiplexing (OFDM) systems with the aim of both enhancing the error performance and reducing the implementation complexity. ... -
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 ... -
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 ... -
Orthogonal time frequency space multiple access using index modulation
Doğan Tusha, Seda; Tusha, Armed; Althunibat, Saud; Qaraqe, Khalid (Institute of Electrical and Electronics Engineers Inc., 2023)Orthogonal time frequency space (OTFS) is a recent two-dimensional modulation technique utilizing delay-Doppler domain and nominated as a promising candidate waveform for beyond 5G communication systems. By leveraging both ... -
Performance analysis of OTFS under in-phase and quadrature imbalance at transmitter
Tusha, Armed; Doğan Tusha, Seda; Yılmaz, Ferkan; Althunibat, Saud; Qaraqe, Khalid; Arslan, Hüseyin (IEEE-Institute of Electrical and Electronics Engineers Inc., 2021)The influence of in-phase and quadrature (IQ) imbalance on the performance of orthogonal time frequency space (OTFS) transmission is investigated in this work. OTFS is a recent two-dimensional transmission scheme with ...
