Application of Non-Orthogonal Multiple Access in LTE and 5G Networks [PDF]
IEEE Communications Magazine, 2015 As the latest member of the multiple access family, non-orthogonal multiple access (NOMA) has been recently proposed for 3GPP LTE and is envisioned to be an essential component of 5G mobile networks.

Trellis-Coded Non-Orthogonal Multiple Access [PDF]
IEEE Wireless Communications Letters, 2020 In this letter, we propose a trellis-coded nonorthogonal multiple access (NOMA) scheme. The signals for different users are produced by trellis coded modulation (TCM) and then superimposed on different power levels. By interpreting the encoding process via the tensor product of trellises, we introduce a joint detection method based on the Viterbi ...

High Reliable Uplink Transmission Methods in GEO–LEO Heterogeneous Satellite Network
Applied Sciences, 2023 As a significant component of non-terrestrial networks, satellite communication has gradually evolved into a heterogeneous topology where the network nodes are classified as low Earth orbit (LEO) and geostationary Earth orbit (GEO) nodes. Considering the

Spectral Efficiency of OTFS Based Orthogonal Multiple Access With Rectangular Pulses [PDF]
IEEE Transactions on Vehicular Technology, 2021 In this paper, we consider Orthogonal Time Frequency Space (OTFS) modulation based multiple-access (MA). We specifically consider Orthogonal MA methods (OMA) where the user terminals (UTs) are allocated non-overlapping physical resource in the delay ...

Analysis of an LSTM-based NOMA Detector Over Time Selective Nakagami-m Fading Channel Conditions
Journal of Telecommunications and Information Technology, 2022 This work examines the efficacy of deep learning (DL) based non-orthogonal multiple access (NOMA) receivers in vehicular communications (VC). Analytical formulations for the outage probability (OP), symbol error rate (SER), and ergodic sum rate for the ...

On the Comparison of Optimal NOMA and OMA in a Paradigm Shift of Emerging Technologies
IEEE Access, 2022 Non-orthogonal multiple access (NOMA) is a better multiple access technique than orthogonal multiple access (OMA), precisely orthogonal frequency division multiple access (OFDMA) scheme, at the conceptual level for fifth-generation (5G) networks and ...

Dynamic User Clustering and Power Allocation for Uplink and Downlink Non-Orthogonal Multiple Access (NOMA) Systems [PDF]
IEEE Access, 2016 Non-orthogonal multiple access (NOMA) has recently been considered as a key enabling technique for 5G cellular systems. In NOMA, by exploiting the channel gain differences, multiple users are multiplexed into transmission power domain and then non ...
