A prototype of uplink NOMA wi-fi with successive interference cancellation: demo

Abstract

New data transmission methods are needed for future Wi-Fi networks to increase throughput and support dense deployments. Wi-Fi networks often consist of devices of different generations, so these methods need to support backward compatibility. Uplink non-orthogonal multiple access (UL-NOMA) is one of the promising methods to address this problem. UL-NOMA increases the spectral efficiency of wireless networks by separating signals by power. However, only a few papers study UL-NOMA in Wi-Fi analytically or with simulations. This demo presents a prototype of a UL-NOMA Wi-Fi communication system and discusses how to implement successive interference cancellation in a UL-NOMA receiver taking into account Wi-Fi limitations.
