Non-Orthogonal Multiple Access (NOMA) for Underwater Acoustic Communication [PDF]
2018 IEEE 88th Vehicular Technology Conference (VTC-Fall), 2018 In this paper we investigate the application of the non-orthogonal multiple access (NOMA) technique for multiuser underwater acoustic (UWA) communication. The NOMA scheme can be implemented using either orthogonal frequency division multiplexing (OFDM) or filterbank multicarrier (FBMC) modulation for waveform shaping.

Downlink Non-Orthogonal Multiple Access (NOMA) in Poisson Networks [PDF]
IEEE Transactions on Communications, 2019 A network model is considered where Poisson distributed base stations transmit to $N$ power-domain non-orthogonal multiple access (NOMA) users (UEs) each {that employ successive interference cancellation (SIC) for decoding}. We propose three models for the clustering of NOMA UEs and consider two different ordering techniques for the NOMA UEs: mean ...

On Power Minimization for Non-orthogonal Multiple Access (NOMA)
IEEE Communications Letters, 2016 We formulate a power optimization problem for non-orthogonal multiple access systems mathematically, and prove its NP-hardness. For tackling the problem, we first identify a convex problem by relaxation. Based on this convexity, we then propose an efficient “relax-then-adjust” algorithm and provide results of performance evaluation.

Resource Allocation in Downlink Non-Orthogonal Multiple Access (NOMA) for Future Radio Access [PDF]
2015 IEEE 81st Vehicular Technology Conference (VTC Spring), 2015 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.

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 ...

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.

On Non-Orthogonal Multiple Access (NOMA) in 5G Systems
The Journal of Korean Institute of Communications and Information Sciences, 2015 The non-orthogonal multiple access (NOMA) is one of the fledging paradigms which next generation radio access technologies are sprouting toward. The NOMA with superposition coding (SC) in the transmitter and successive interference cancellation (SIC) at the receiver comes with many desirable features and benefits over orthogonal multiple access (OMA ...

Non-Orthogonal Multiple Access (NOMA) Dynamic Power Allocation in 5G Networks
Wasit Journal of Engineering Sciences, 2022 Abstract The thought of non-orthogonal multiple access (NOMA) are given as a potential radio access method for versatile correspondence networks past the fourth era (4G). As opposed to current long haul development radio access procedures, non-symmetrical different access involves the power space for client multiplexing at the transmitter and ...
