In this paper, we address a practical but adverse problem that successive interference
cancellation (SIC) is imperfect in a massive non-orthogonal multiple access (NOMA) system …

This paper considers the security issue of the fifth-generation wireless networks with
massive connections, where multiple eavesdroppers aim to intercept the confidential …

This paper seeks to answer a simple but fundamental question: what role can non-
orthogonal multiple access (NOMA) play in massive multi-in multi-out (MIMO)? It is well …

We investigate the application of non-orthogonal multiple access (NOMA) with successive
interference cancellation (SIC) in downlink multiuser multiple-input multiple-output (MIMO) …

This paper investigates the throughput improvement of cell-free massive multiple-input
multiple-output (MIMO) systems by non-orthogonal multiple access (NOMA) for future …

A cell-free massive multiple-input multiple-output system with non-orthogonal multiple-
access (NOMA) is investigated. An achievable sum rate is derived and compared against …

Non-orthogonal multiple access (NOMA) has recently been considered as a key enabling
technique for 5G cellular systems. In NOMA, by exploiting the channel gain differences …

The non-orthogonal multiple access (NOMA) allows one subcarrier to be allocated to more
than one user at the same time in an orthogonal frequency division multiplexing (OFDM) …

We investigate the achievable rate of a hybrid cell-free (CF) massive multiple-input multiple-
output (MIMO) non-orthogonal multiple-access (NOMA) underlaid below a primary massive …

Multi-antenna non-orthogonal multiple access (NOMA) is a promising technique to
significantly improve spectral efficiency and support massive access, which has received …
