PERFORMANCE ANALYSIS OF LARGE INTELLIGENT SURFACE-ASSISTED NON-ORTHOGONAL MULTIPLE ACCESS FOR 6G WIRELESS NETWORKS

Abstract

In order to establish sixth-generation (6G) wireless networks, we must implement innovative technology that can accommodate increased data rates, multiple connections, and improved spectral efficiency. Reconfigurable intelligent surfaces, also known as large intelligent surfaces (LIS), enable clever wireless environment control. Through power-domain multiplexing, Non-Orthogonal Several Access (NOMA) effectively enables numerous users to use the same spectrum. With a focus on critical elements like spectrum efficiency, energy efficiency, outage probability, and system throughput, this study investigates the performance of LIS-assisted NOMA systems for 6G networks. When multiple people speak simultaneously, the combination of LIS and NOMA increases coverage, reduces interference, and improves signal quality. The findings show that LIS-assisted NOMA works significantly better than traditional systems, making it a viable option for the upcoming generation of wireless communication.
