This paper focuses on the latest research and innovations in fundamental next-generation
multiple access (NGMA) techniques and the coexistence with other key technologies for the …

In this paper, we introduce a novel framework consisting of hybrid bit-level and generative
semantic communications for efficient downlink image transmission within space-air-ground …

We have developed a model for a wireless powered bi-modal communication system that
dynamically switches between conventional and semantic communication to leverage the …

In traditional non-orthogonal multiple access (NOMA) systems, the secondary user often
encounters decoding challenges caused by a lower signal-to-noise ratio (SNR) as it is …

In this paper, we address the challenge of enhancing communication efficiency in non-
orthogonal multiple access (NOMA) networks by exploring a novel paradigm known as …

The increased use of heterogeneous and homogeneous smart devices in smart homes
increases the rate of energy consumption. Among the plethora of smart devices within a …

This thesis focuses on improving the performance of multiple access networks (MAC
networks) through the use of appropriate metrics that evaluate the age of information. These …
