A Novel Downlink IM-NOMA Scheme
IEEE Open Journal of the Communications Society, 2021 In the next generations of communication systems, resources' scarcity devolves to a more critical point as a consequence of the expected massive number of users to be served. Furthermore, the users' contradicting requirements on quality of service forces

RIS Partition-Assisted Non-Orthogonal Multiple Access (NOMA) and Quadrature-NOMA with Imperfect SIC
IEEE Transactions on Wireless Communications, 2022 Reconfigurable intelligent surface (RIS)-assisted power-domain non-orthogonal multiple access (PD-NOMA) system has emerged as a revolutionary technology to enhance the spectrum efficiency for future wireless networks. This work introduces two novel RIS systems, namely, RIS partition-assisted (RISP) PD-NOMA (RISP-PD-NOMA) and RISP-Quadrature NOMA (RISP ...

Outage Probability analysis of Power Domain MISO-NOMA in Rayleigh Fading Channel
Sir Syed University Research Journal of Engineering and Technology, 2022 The multiple access technique of the current wireless communication system depends on the orthogonal multiple access (OMA) technique. The availability of orthogonal resources is limited in OMA and cannot support the increasing demand for a large number ...

Partial-Beam Non-Orthogonal Multiple Access (PB-NOMA) With Fuzzy Clustering
IEEE Wireless Communications Letters, 2021 This letter proposes a partial-beam non-orthogonal multiple access (PB-NOMA) system for millimeter wave (mmWave) channels. In the proposed system, the user terminals (UT)s partially belong to different user groups and power-domain partial NOMA (P-NOMA) technique is exploited in their allocated spectrum.
