As a symbol-level precoding scheme, constructive interference precoding (CIP) has been
demonstrated its superiority in multi-antenna orthogonal multiple access (OMA) systems. By …

A novel reconfigurable intelligent surface (RIS) aided non-orthogonal multiple access
(NOMA) downlink transmission framework is proposed. We formulate a long-term stochastic …

We propose a new framework of uplink grant-free non-orthogonal multiple access (NOMA)
composed of user activity detection, channel estimation, and data detection. Since the …

Non-orthogonal multiple access (NOMA) is an effective technique to improve spectral
efficiency and connectivity level of multi-user systems by means of successive interference …

In most existing works on non-orthogonal multiple access (NOMA), the decoding order of
successive interference cancellation (SIC) is prefixed and based on either the users' …

This paper considers a multiple-input multiple-output non-orthogonal multiple access
(NOMA) downlink transmission system with different linear beamforming techniques, where …

Non-orthogonal multiple access (NOMA) is highly expected to increase system throughput
and accommodate massive connectivity by allowing multiple users to share the same …
