Performance Analysis of MIMO NOMA based Wireless Network for 5G and beyond under Rayleigh Fading Channel

In this research endeavor, the amalgamation of two cutting-edge technologies, Multiple-Input Multiple-Output (MIMO) and Non-Orthogonal Multiple Access (NOMA), offers a solution to the challenges posed by the 5G cellular system and its futuristic counterparts. The study focuses on wireless networks operating in Rayleigh fading channels, which are challenging conditions. The main objectives of the research are to derive closed-form expressions for Bit Error Rate (BER) and the outage probability equation for Downlink (DL) NOMA. Additionally, the investigation extends beyond 5G into the unexplored territory of 6G wireless technology, where the impact of dynamic bandwidth variations is explored. Furthermore, the study evaluates the system's performance by examining the BER, shedding light on the capabilities of 5G and its evolutionary successors. The findings from this research could significantly contribute to advancements in wireless communication technologies.
