Project Abstract

This research examines the critical area of wireless spectrum access, focusing on Non-Orthogonal Multiple Access (NOMA) and Orthogonal Multiple Access (OMA) for enhancing wireless spectrum efficiency in 5G and beyond 5G networking (6G). The urgency to optimize spectrum use is driven by the fast growth in data traffic and device connectivity demands, necessitated by emerging technologies, which suggests integrating Non-Orthogonal Multiple Access with Orthogonal Multiple Access approaches. The purpose of the study is to assess and contrast NOMA and OMA in terms of how well they can enhance network performance and spectral efficiency for 5G and beyond 5G networks (6G). The goal is to find the perfect approach that provides the best capacity, response time, and overall efficiency under actual network conditions. The study methodology creates simulations to model the performance of NOMA and OMA under different network settings using MATLAB and analyze the achievable effective capacity of two-user NOMA and OMA systems under varying signal-to-noise ratios (SNRs) and power allocation coefficients. Graph theory techniques are used to optimize spectrum allocation, which is essential for increasing network throughput and lowering interference. The results show that NOMA performs much better than OMA under low signal-to-noise ratio (SNR) circumstances, offering higher Effective Capacity (EC) in various user scenarios. The benefits of NOMA become even more noticeable at high SNRs. At the successful completion of this project, this research will show how NOMA outperforms OMA in spectral efficiency for future wireless networks, particularly at higher SNRs by allowing multiple users to share the same frequency bands. This results in increased network capacity, user throughput, and energy efficiency. The adoption of NOMA could lead to more strong, accessible, and efficient wireless networks, ready to meet the challenges of an increasingly connected world.
