The development of Industrial Internet of Things (IIoT) has been limited due to the shortage
of spectrum resources. Based on cognitive radio, the cognitive IIoT (CIIoT) has been …

The 5G cellular network employs non-orthogonal multiple access (NOMA) to enhance
network connectivity and capacity, and device-to-device (D2D) communications to improve …

As a promising physical layer technique, nonorthogonal multiple access (NOMA) can admit
multiple users over the same space-time resource block, and thus improve the spectral …

Non-orthogonal multiple access (NOMA) is the technique proposed for multiple access in
the fifth generation (5G) cellular network. In NOMA, different users are allocated different …

We consider the framework of uplink transmission and interference constraint for new
system model to provide multiple access scheme for fifth generation (5G) wireless …

This paper aims at shedding light on the impact of unsaturated traffic on the performance of
uplink non-orthogonal multiple access (NOMA) transmissions. Nevertheless, the …

In this work, we evaluate the outage probability of a two-user network-coded cooperative
(NCC) uplink system subjected to non-orthogonal multiple access (NOMA). We consider that …

Probabilistic shaping (PS) combined with bipolar amplitude shift keying modulation is a
promising transmission scheme to increase spectral efficiency. Different from the existing …

Non‐orthogonal multiple access (NOMA) makes multiple users to overload the same
wireless resources by utilising the superposition coding principle, so that NOMA can …

In this paper, we consider a two-way relay non-orthogonal multiple access (TWR-NOMA)
system with residual hardware impairments (RHIs) and channel estimation errors (CEEs) …
