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 ...

Performance Analysis of IRS-Aided NOMA Communications in the Presence of Imperfect SIC [PDF]
Journal of Electromagnetic Engineering and Science, 2021 The intelligent reflecting surface (IRS) is expected to be a promising technique to achieve a robust spectrum and energy efficiency. This paper investigates the advantages of IRS in enhancing performance of non-orthogonal multiple access (NOMA ...

IET Networks, EarlyView., 2023 We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...

A Case of Gastric Neuroendocrine Tumor With a Raspberry-Like Appearance on the Background of Acid-Suppressive Therapy-Related Gastropathy. [PDF]
DEN OpenABSTRACT We report the case of a 52‐year old man who was referred to our institution after a routine health check identified an asymptomatic gastric polyp. The medical history of the patient included reflux esophagitis, for which he had been treated with vonoprazan 10 mg daily for 6 years after initially receiving proton pump inhibitors.
