Coordinated Beamforming for Multi-Cell Non-Orthogonal Multiple Access-Based Spatial Modulation
This paper proposes coordinated beamforming (CB) that works over non-orthogonal multiple access (NOMA) scheme integrated with spatial modulation (SM), termed as CB NOMA-SM, to improve capacity and user fairness. User capacity, ergodic sum capacity (ESC),

A Novel Downlink IM-NOMA Scheme
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
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
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 ...

Resource Allocation in Downlink Non-Orthogonal Multiple Access (NOMA) for Future Radio Access [PDF]
This paper investigates a new strategy for radio resource allocation applying a non-orthogonal multiple access (NOMA) scheme. It calls for the cohabitation of users in the power domain at the transmitter side and for successive interference canceller (SIC) at the receiver side.
