11. Non-Orthogonal Multiple Access

The wireless medium must be shared between multiple devices that want to access various services simultaneously. To avoid interference, the devices have traditionally taken turns, which is known as orthogonal multiple access. The use of non-orthogonal multiple access (NOMA) techniques, where the devices are interfering in a controlled manner, was a popular theme in the research leading up to 5G. In this episode, Emil Björnson and Erik G. Larsson discuss the different forms of NOMA, and what their benefits and weaknesses are. They discuss what role NOMA plays in 5G and might play in future wireless technologies. To learn more, they recommend the article “Is NOMA Efficient in Multi-Antenna Networks? A Critical Look at Next Generation Multiple Access Techniques” (https://arxiv.org/abs/2101.04802). Music: On the Verge by Joseph McDade.
