Cognition and Cooperation in Interfered Multiple Access Channels
Entropy, 2017 In this work, we investigate a three-user cognitive communication network where a primary two-user multiple access channel suffers interference from a secondary point-to-point channel, sharing the same medium. While the point-to-point channel transmitter—

Non-orthogonal Multiple Access (NOMA) with Asynchronous Interference Cancellation [PDF]
, 2015 Non-orthogonal multiple access (NOMA) allows allocating one carrier to more than one user at the same time in one cell. It is a promising technology to provide high throughput due to carrier reuse within a cell.
