Performance Evaluation of Uplink Non-Orthogonal Multiple Access with Reservation Signals in Wi-Fi Networks

Uplink Non-Orthogonal Multiple Access (UL NOMA) is a promising technology that can improve the spectral efficiency and bandwidth of Wi-Fi networks. The use of UL NOMA allows multiple stations to transmit data to an access point in the same frequency–time resource. Reservation signals are used to organize UL NOMA data transmission. In this paper, we develop an analytical model that makes it possible to evaluate the performance of UL NOMA with a high accuracy at various Wi-Fi network parameters.
