Coming to the introduction, Non-Orthogonal Multiple Access is a technology used in wireless communication systems to improve spectral efficiency and increase the capacity of the network. Unlike traditional multiple access techniques where orthogonal resources are allocated to different users, NOMA allows multiple users to share the same time-frequency resources simultaneously by utilizing power domain multiplexing. These are the Key Features of NOMA 1. Power Domain Multiplexing: NOMA allocates different power levels to multiple users in the same time-frequency resource block. Users with weaker channel conditions are assigned higher power levels, while users with stronger channel conditions receive lower power levels. 2. Superposition Coding and Successive Interference Cancellation (SIC): 3. Spectral Efficiency: 4. Improved Connectivity and User Experience: 5. And next, we can use this technology for 5G & BEYOND: |
