Optical Beam Steerable and Flexible Data Rate Orthogonal Frequency Division Multiplexing Non-Orthogonal Multiple Access (OFDM-NOMA) Visible Light Communication

We propose and demonstrate visible-light-communication (VLC) system using spatial-light-modulator (SLM) and orthogonal-frequency-division-multiplexing non-orthogonal-multiple access (OFDM-NOMA), illustrating the flexibilities of optical-beam steering and data-rate allocation for multiple users.
