In this paper, we propose a distributed cluster formation (CF) and resource allocation (RA)
framework for non-ideal non-orthogonal multiple access (NOMA) schemes in …

In this paper, we develop various beamforming techniques for downlink transmission for
multiple-input single-output nonorthogonal multiple access (NOMA) systems. First, a …

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 …

We propose the Variational Shape Learner (VSL), a generative model that learns the
underlying structure of voxelized 3D shapes in an unsupervised fashion. Through the use of …

With the increasing user density of wireless networks, various user partitioning techniques or
algorithms segregate users into smaller, more manageable clusters. The benefit of user …

Cooperative and cognitive non-orthogonal multiple access (CCR-NOMA) has been
recognized as a promising technique to overcome spectrum scarcity and massive …

In this article, a comprehensive strategy of user clustering and power allocation is
investigated in downlink hybrid non-orthogonal multiple access (NOMA) networks. More …

Non-orthogonal multiple access (NOMA) has potentials to improve the performance of multi-
