A Simple Design of IRS-NOMA Transmission [PDF]

open access: yesIEEE Communications Letters, 2019
This letter proposes a simple design of intelligent reflecting surface (IRS) assisted non-orthogonal multiple access (NOMA) downlink transmission. In particular, conventional spatial division multiple access (SDMA) is used first at the base station to ...

Error Probability Analysis of NOMA-based Diamond Relaying Network [PDF]

open access: yesin IEEE Transactions on Vehicular Technology, vol. 69, no. 2, pp. 2280-2285, Feb. 2020, 2020
Non-orthogonal multiple access (NOMA)-based cooperative relaying systems (CRS) are very promising to overcome spectral inefficiency of conventional cooperative communications. Although NOMA-CRS have great recent attention, almost all studies investigate NOMA-CRS only in terms of capacity and outage probability.

Transmitted Data Security in Non-Orthogonal Multiple Access Networks with Directional Modulation Based on User Location [PDF]

open access: yesInternational Journal of Information and Communication Technology Research, 2023
In Non-orthogonal multiple access, a user with a weaker channel gain is assigned more power than a user with a stronger channel. This type of power allocation allows the strong user (SU) to apply the successive interference cancellation (SIC) method that
