Optical Beam Steerable and Beam Dividable of Non-Orthogonal Multiple Access (NOMA) Signal with Low-Density Parity-Check (LDPC) for Multi-User Optical Wireless Communication System

Abstract

We propose a spatial-light-modulator (SLM)-enabled optical beam steerable and beam dividable optical-wireless-communication (OWC) using orthogonal-frequency-division-multiplexing non-orthogonal-multiple-access (OFDM-NOMA) and low-density-parity-check (LDPC). Three-layer successive-interference-cancellation (SIC) is experimentally demonstrated.
