In this paper, we analyze the outage probability and secrecy capacity of a non-orthogonal
multiple access (NOMA) system in the presence of an eavesdropper. In order to enhance …

In this paper, we consider the physical layer security of a downlink non-orthogonal multiple
access (NOMA) system, in which users' quality of service (QoS) requirements are …

A new design of non-orthogonal multiple access (NOMA) is explored in this study under
secrecy outage probability performance considerations. In particular, the Amplify-and …

This paper investigates secure transmission for non-orthogonal multiple access (NOMA)
systems where the imperfect successive interference cancellation (SIC) is considered at …

In 5G wireless communication networks, Non-Orthogonal Multiple Access (NOMA) has
attracted much attention in recent years. This paper investigates physical layer security of a …

A key feature of the non-orthogonal multiple access (NOMA) technique is that users with
better channel conditions have prior information about the messages of other users. The …

In this work, we investigate the relationship between the reliability and security of a typical
two-user downlink non-orthogonal multiple access (NOMA) communication system. The …

Non-orthogonal multiple access (NOMA) has been recognized as a promising technique for
providing high data rates in 5G systems. This letter is to study physical layer security in a …

With non-orthogonal multiple access (NOMA) in a passive eavesdropping scenario, we
tackle the maximization of the secrecy rate for the strong user subject to a maximum …

This paper proposes a new design of non-orthogonal multiple access (NOMA) under
secrecy considerations. We focus on a NOMA system, where a transmitter sends confidential …
