  Abstract

NOMA shares frequency and time resources and multiplexes signals in the power domain. NOMA shows higher efficiency than conventional OMA in terms of frequency efficiency, but BER performance is relatively poor. In order to improve this, NOMA based on LIS composed of reflective elements capable of controlling the channel environment is being studied. However, in the conventional LIS-NOMA, LIS perform channel control to only one user. As a result, there was a large difference between NOMA users" BER performance. Therefore, in this paper, we propose a downlink splitting LIS-NOMA system that supports multiple users by dividing reflective elements of LIS. Through simulation, we compare the BER performance of the conventional NOMA and LIS-NOMA and splitting LIS-NOMA systems. As a result of simulation, the proposed system shows improved BER performance on average compared to the conventional LIS-NOMA.
