Clipping noise mitigation using partial transmit sequence for optical OFDM systems

Esat Ankaralı, Zekeriyya; Hussain, Syed Imtiaz; Abdallah, Mohamed; Qaraqe, Khalid; Arslan, Hüseyin; Haas, Harald (Institute of Electrical and Electronics Engineers Inc., 2014)

Orthogonal frequency division multiplexing (OFDM) is a promising technology to achieve higher data rates in optical wireless communication (OWC) systems. Unlike single carrier techniques, OFDM can easily handle inter-symbol ...
Joint subcarrier and antenna state selection for cognitive heterogeneous networks with reconfigurable antennas

Yılmaz, Mustafa Harun; Abdallah, Mohamed; El-Sallabi, Hassan; Chamberland, Jean-Francois; Qaraqe, Khalid; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers, 2015)

Reconfigurable antennas (RA) offer an emerging technology that allows wireless devices to alter their antenna states determined by different radiation patterns to maximize received signal strength. In this paper, we consider ...
