For the last few decades, wireless communication has been facing a technological
revolution. High data rate and continuous connectivity are the necessities because the …

The rapid increase in data traffic caused by the proliferation of smart devices has spurred the
demand for extremely large-capacity wireless networks. Thus, faster data transmission rates …

We consider an intelligent reflecting surface (IRS) wireless-powered NOMA Internet-of-
Things (IoT) network, where multiple NOMA IoT devices can communicate with access point …

Due to the increasingly complicated communication scenarios and network architectures as
well as growing traffic demands for high speed connectivity, dynamic spectrum allocation in …

Spectrum bands are the backbone of wireless networks. Every user is allocated a fraction of
the spectrum from available fixed spectrum band. But, the fixed available spectrum band …

Recently, massive multiple input multiple output (MIMO) channel tracking in the fifth
generation (5G) new radio (NR) systems has attracted intensive interest. By exploiting the …

Sparse code multiple access (SCMA) is one of the most intensively investigated non-
orthogonal multiple access (NOMA) techniques for the fifth generation communication (5G) …

This paper investigates the transmitter and receiver beamforming (TB and RB) for over-the-
air computation (AirComp) in massive multiple-inputs and multiple-outputs (MIMO) systems …

Non-orthogonal multiple access (NOMA) is consid-ered an important candidate for the next-
generation cellular networks to address the issue of exponentially growing data traffic from …

5G communication systems and beyond are envisioned to support an extremely diverse set
of use cases with different performance requirements. These different requirements …
