Performance analysis of a 5 Gbps PAM-4 modulated visible light optical wireless communication link: impact of transmission power, receiver field-of-view, and concentrator design parameters

Abstract This paper presents a detailed performance study of a visible light communication (VLC) link using 4-level pulse amplitude modulation (PAM-4) at a 450 nm wavelength. Link performance is systematically evaluated as a function of transmission distance across varying transm...
