In this paper, a novel approach is introduced to study the achievable delay-guaranteed
secrecy rate, by introducing the concept of the effective secrecy rate (ESR). This study …

We study the secrecy transmission of uplink non-orthogonal multiple access (NOMA) with
single antenna and multi-antenna users in presence of an eavesdropper. Two phases are …

We investigate physical layer security of an uplink NOMA system consisting of one base
station, multiple users and one eavesdropper. During each uplink transmission, two users …

The key idea of non-orthogonal multiple access (NOMA) is to serve multiple users in the
same resource block to improve the spectral efficiency. Whereas due to the resource …

The secrecy performance of a nonorthogonal multiple access (NOMA) system is examined
in this study by employment of a dual‐hop decode‐and‐forward (DF) relay under existence …

To enhance the secrecy of wireless transmission, we propose a cooperative user relaying
NOMA scheme, in which the near user works in full-duplex mode by transmitting jamming …

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 …

In a downlink non-orthogonal multiple access (NOMA) system, the reliable transmission of
cell-edge users cannot be guaranteed due to severe channel fading. On the other hand, the …

We have proposed and analyzed secrecy performance of a network architecture which
contains a source, two destinations, a friendly jammer (FJ) and an eavesdropper (Eve). To …

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