A Novel Transmit Array Structure for Optical Spatial Modulation
Çoğalan, Tezcan; Haas, Harald; Panayırcı, Erdal (IEEE, 2019)The performance of multiple input single output (MISO) and multiple input multiple output (MIMO) systems is limited by spatial channel correlation. This limitation becomes particularly severe in light lidelity (LiFi) ... -
Physical-layer security in visible light communications
Yeşilkaya, Anıl; Çoğalan, Tezcan; Erküçük, Serhat; Şadi, Yalçın; Panayırcı, Erdal; Haas, Harald; Poor, Harold Vincent (Institute of Electrical and Electronics Engineers Inc., 2020)Optical wireless communications (OWC) and its potential to solve physical layer security (PLS) issues are becoming important research areas in 6G communications systems. In this paper, an overview of PLS in visible light ... -
Physical-Layer Security With Optical Generalized Space Shift Keying
Panayırcı, Erdal; Yeşilkaya, Anıl; Çoğalan, Tezcan; Poor, H. Vincent; Haas, Harald (Ieee-Inst Electrıcal Electronıcs Engıneers Inc, 2020)Spatial modulation (SM) is a promising technique that reduces inter-channel interference while providing high power efficiency and detection simplicity. In order to ensure the secrecy of SM, precoding and friendly jamming ... -
Power Control-Based Multi-User Li-Fi Using A Compound Eye Transmitter
Çoğalan, Tezcan; Haas, Harald; Panayırcı, Erdal (IEEE, 2015)In visible light communications (VLC) the transmitted signal is non-negative and real valued and these characteristics constrain the signal space and provide new challenges for waveform design in a multi-user system. In ...
