Generalized parabolic function for reduced PAPR in optical OFDM systems

Abstract In visible light communication (VLC) systems, orthogonal frequency division multiplexing (OFDM) is often used, but its high peak-to-average power ratio (PAPR) reduces system efficiency. To address the significant PAPR challenge in direct current–biased optical OFDM (DCO-...

LED dimming and nonlinearity effects on link selection in hybrid VLC/RF networks

Abstract The codeployment of visible light communication (VLC) and radio frequency (RF) technologies has attracted research interest for indoor capacity enhancement. Many existing hybrid VLC/RF link selection schemes assume that the LED behaves as a perfectly linear device, an as...

A low-complexity optical OFDM physical layer for AI-native 6G visible light communication networks

Abstract The sixth generation (6G) networks native to artificial intelligence (AI) are expected to enable intelligent and real-time communication services, which increase the processing needs across the network nodes. Therefore, future visible light communication (VLC) systems ba...
