Non-Orthogonal Multiple Access (NOMA) for Cellular Future Radio Access

IEEE Vehicular Technology Conference, 2013
This paper presents a non-orthogonal multiple access (NOMA) concept for cellular future radio access (FRA) towards the 2020s information society. Different from the current LTE radio access scheme (until Release 11), NOMA superposes multiple users in the

Non-Orthogonal Multiple Access Assisted Secure Computation Offloading via Cooperative Jamming

IEEE Transactions on Vehicular Technology, 2022
In this paper, we investigate non-orthogonal multiple access (NOMA) assisted secure computation offloading under the eavesdropping-attack, in which a malicious node overhears the edge-computing user's (EU’s) offloading transmission to the edge-computing ...

Optimal User Pairing for Downlink Non-Orthogonal Multiple Access (NOMA)

IEEE Wireless Communications Letters, 2019
In this letter, we explore user pairing in a downlink non-orthogonal multiple access (NOMA) network. As power allocation inherently intertwines with user pairing, a joint user pairing and power allocation problem is considered to optimize the achievable ...

On the Performance of Non-Orthogonal Multiple Access in Short-Packet Communications

IEEE Communications Letters, 2018
This letter investigates the performance of non-orthogonal multiple access (NOMA) in short-packet communications. We aim to answer a fundamental question–for given reliability requirements of users: how much physical-layer transmission latency can NOMA ...

Frequency Hopping Non-Orthogonal Multiple Access

International Conference on Wireless Communications and Signal Processing, 2023
Non-orthogonal multiple access (NOMA) has circumvented OMA’s connectivity limitations, providing new possibilities to achieve a larger connection. One of the most popular uplink NOMA schemes is sparse code multiple access (SCMA).
