Abstract

The NOMA-based VLC systems require channel state information (CSI) at the transmitter, which increases the computational complexity and feedback overhead. To tackle this challenge, this paper proposes an effective NOMA scheme for indoor VLC systems, in which the quantized CSI, instead of the full CSI, is used for user pairing and power allocation at the transmitter. Simulation results show that although the performance has some fluctuation in the single trial, the average performance of random trials is almost the same as that of the traditional scheme.
