Abstract This work presents a novel partially overlapping near-user non-orthogonal multiple access (P-NU-NOMA) scheme for a visible light communication (VLC) system, namely, the P-NU-NOMA VLC system. Specifically, the near user partially overlaps with the far user over a fraction of bandwidth. Under imperfect channel state information (CSI) and successive interference cancellation (SIC), the achievable rate analysis of P-NU-NOMA over a downlink line-of-sight (LOS) VLC channel is reported.

Visible light communication (VLC) allows white LEDs to communicate while lighting, which improves resource consumption. Multiple relay approaches can be employed in conjunction with cooperative communications to achieve large gains in spatial diversity, expand the coverage, and possibly boost system capacity. In this paper, the nonorthogonal multiple access (NOMA) cooperative techniques for VLC systems using on–off keying (OOK) and L-pulse-position modulation (L-PPM) are proposed.

Abstract In recent years, visible light communication (VLC) has emerged as a potential technique for beyond 5G communication networks. In this study, an angular diversity receiver (ADR) is used to propose a multiple-input multiple-output (MIMO) VLC system employing $\textit{L}$-pulse position modulation ($L$-PPM).
