Faster-Than-Nyquist Asynchronous NOMA Outperforms Synchronous NOMA [PDF]
IEEE Journal on Selected Areas in Communications, 2022 Faster-than-Nyquist (FTN) signaling aided non-orthogonal multiple access (NOMA) is conceived and its achievable rate is quantified in the presence of random link delays of the different users. We reveal that exploiting the link delays may potentially lead to a signal-to-interference-plus-noise ratio (SINR) gain, while transmitting the data symbols at ...

The Performance Evaluation of NOMA for 5G Systems Using Automatic Deployment of Multi Users [PDF]
International Journal of Electronics and Telecommunications, 2022 Non-Orthogonal Multiple Access (NOMA) in the fifth generation (5G) system is one of the optimistic technologies for wireless radio access networks. Compared to orthogonal multiple accesses (OMA) reduce the spectral efficiency; NOMA provides the best ...

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