Adaptive unipolar MIMO-OFDM for visible light communications
Al-Nahhal, Mohamed; Basar, E.; Uysal, Murat (IEEE, 2019)Unipolar orthogonal frequency division multiplexing (U-OFDM) appears as an attractive optical OFDM solution for emerging visible light communication (VLC) systems. This paper proposes spectral efficiency improvement for ... -
Flexible generalized spatial modulation for visible light communications
Al-Nahhal, Mohamed; Başar, E.; Uysal, Murat (IEEE, 2021-01)Adaptive spatial modulation (ASM) varies the modulation size across the transmit light-emitting diodes (LEDs) to improve the overall spectral efficiency of visible light communication (VLC) systems. This article proposes ... -
Magnitude and wrap-phase OFDM for MIMO visible light communication systems
Al-Nahhal, Mohamed; Başar, E.; Uysal, Murat (IEEE, 2021-07)Generalized light emitting diode (LED) index modulation (GLIM) has been proposed as an effective multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) scheme for visible light communications ... -
Transmit laser selection for underwater visible light communication systems
Elamassie, Mohammed; Al-Nahhal, Mohamed; Kızılırmak, R. Ç.; Uysal, Murat (IEEE, 2019)Visible light communication (VLC) has the potential to serve as a high-speed underwater wireless connectivity solution to support real-time image and video transmission.
