Abstract
With the rapid advancement of wireless communication technologies and the increasing
demand for high-quality services, communication networks face significant challenges in
efficiently utilizing the available spectrum. These challenges include increasing network
capacity, enabling massive connectivity, enhancing data rates, reducing latency, and
minimizing spectrum bandwidth requirements. Traditional approaches, such as Orthogonal
Multiple Access (OMA), allocate dedicated resources to each user. However, as the number
of users increases, OMA suffers from efficiency limitations. For this reason, the wireless
communication research community has been actively exploring more advanced multipleaccess technologies to improve resource efficiency. In this context, Non-Orthogonal Multiple
Access (NOMA) has emerged as an innovative solution, particularly for fifth-generation (5G)
and beyond networks. In this thesis, we study the performance evaluation of OMA and
NOMA systems in downlink networks, focusing on performance analysis in the presence of
energy harvesting. NOMA stands out by providing better data transmission rates while
reducing information loss. We propose an innovative pairing strategy for a hybrid NOMA
system incorporating a fair power allocation algorithm in the downlink network to enhance
system performance and user satisfaction. This strategy aims to achieve high performance
while ensuring fairness among users. It is evident that NOMA represents the future of
wireless communications and plays a crucial role in realizing next-generation 5G and beyond
