Performance Evaluation of Uplink NOMA in Wi-Fi Networks

Non-orthogonal multiple access (NOMA) is a key technology for future wireless systems. Keeping the number of antennas on the devices unchanged, NOMA increases the spectral efficiency of the wireless system and raises the aggregated system throughput. For this reason, NOMA is a very attractive technology for implementation in future Wi-Fi standards that will come after Wi-Fi 7. The paper proposes and evaluates uplink NOMA in Wi-Fi, The obtained results show approximately 100% gain in throughput of the uplink NOMA comparing with the legacy Wi-Fi systems.
