On Clustering and Channel Disparity in Non-Orthogonal Multiple Access (NOMA)

, 2019
Non-orthogonal multiple access (NOMA) allows multiple users to share a time-frequency resource block by using different power levels. An important challenge associated with NOMA is the selection of users that share a resource block. This is referred to as clustering, which generally exploits the channel disparity (i.e. distinctness) among the users. We

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.\ud \ud In this thesis, a novel interference cancellation (IC) technique is proposed for asynchronous NOMA systems, which uses multiple symbols

Energy efficient resource allocation for Non-Orthogonal Multiple Access (NOMA) systems

, 2017
Non-orthogonal multiple access (NOMA) is a promising technique for the fifth generation (5G) mobile communication due to its capability of achieving high spectral efficiency and high data rate. A popular NOMA scheme uses power domain to achieve multiple access.
