DOI: 10.1016/j.ijleo.2018.11.118

Abstract: Abstract This paper proposes a hybrid orthogonal frequency division multiplexing (OFDM) modulation termed as hybrid DC-biased asymmetrically-clipped pulse-amplitude-modulated OFDM (HDAP-OFDM) for providing power efficient communication and dimming control for light fidelity (LiFi) schemes. The proposed… read more here.

DOI: 10.1016/j.optcom.2019.02.008

Abstract: Abstract Optical-orthogonal frequency division multiplexing (O-OFDM) is regarded as an effective scheme for intensity modulation and direct detection (IM-DD) based visible light communication (VLC) systems. State-of-the-art O-OFDM approaches complying with IM-DD constraints are; direct-current (DC)… read more here.

DOI: 10.1109/lcomm.2023.3339648

Abstract: The application of DFT precoding in mitigating peak-to-average power ratio issues in asymmetrically clipped orthogonal frequency division multiplexing (ACO-OFDM) under power constraints is well-established. However, analytical solutions for assessing the communication performance of power-constrained ACO-OFDM… read more here.
