Non-Orthogonal Frequency Division Multiple Access [PDF]
2020 IEEE 91st Vehicular Technology Conference (VTC2020-Spring), 2020 This paper proposes a frequency-domain multiple user access scheme termed non-orthogonal frequency division multiple access (NoFDMA), which maintains the same data rate per user while allowing more users to access via non-orthogonal user overlapping in a given spectral band.

Cooperative Non-Orthogonal Multiple Access With Physical Layer Network Coding [PDF]
IEEE Access, 2019 Physical layer network coding (PNC) has been proposed for information exchange between a pair of users assisted by a relay. However, the spectral efficiency of PNC reduces when the number of user pairs increases due to the requirement of orthogonal ...

Performance improvement of non-orthogonal multiple access scheme using code division multiplexing
International Journal of Distributed Sensor Networks, 2017 Currently, the standardization of fifth-generation mobile communication system (5G), which realizes 10 Gbps transmission, is in progress. In mobile communications, it is generally difficult to perform high-capacity transmission because of channel fading.

Non-Orthogonal Multiple Access: A Unified Perspective [PDF]
IEEE Wireless Communications, 2018 Non-orthogonal multiple access (NOMA) is a promising technique for future mobile communication systems, which can approach multiuser channel capacity by sharing the same time-frequency resources with multiple users. In this article, we provide a unified framework for NOMA and review the principles of various NOMA schemes in different domains with the ...

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 ...
