Uplink NOMA demo accepted for IEEE INFOCOM
The IEEE International Conference on Computer Communications (INFOCOM), a top-ranked conference on networking in the research community, will take place May 2-5. The demo paper “Receiver Design and Frame Format for Uplink NOMA in Wi-Fi”, authored by WNL members Roman Zlobin, Aleksey Kureev, and Evgeny Khorov, is accepted for this conference. The video of the demo will be available soon.
Uplink non-orthogonal multiple access (UL-NOMA) is one of the promising techniques for future Wi-Fi. UL-NOMA improves spectral efficiency in a heterogeneous Wi-Fi network where the qualities of the channel between the access point and associated stations are significantly different. In UL-NOMA, various stations transmit several data streams to the access point in the same frequency and time resources. However, incorporating UL-NOMA in the Wi-Fi technology requires new channel estimation and phase compensation mechanisms as well as new frame formats that allow separate reception of multiple frames at the access point and ensure backward compatibility with existing Wi-Fi devices. This demo presents a first-ever prototype of the UL-NOMA Wi-Fi system and briefly evaluates its efficiency.
