    Outage probability analysis for noma over Alpha-Mu generalized fading channel
    (İstanbul Gelişim Üniversitesi Lisansüstü Eğitim Enstitüsü, 2023) Al Safah, Rusul Abbas Abed
    Non-orthogonal multiple access (NOMA) is a promising technology that can meet the needs of wireless communication generations, such as the fifth generation (5G) and beyond. The NOMA can provide high spectral/energy efficiency, high connectivity, and low latency. Unlike orthogonal multiple access (OMA) techniques that use orthogonal resources, NOMA allocates non-orthogonal resources to multiple users, resulting in higher spectral efficiency. In the power domain NOMA, users are superimposed with different power levels based on their channel conditions, and receivers use successive interference cancellation (SIC); hence a good balance between system throughput and user fairness can be provided. The thesis examines the system's outage probability (OP) performance in ?-? generalized fading channels. In particular, we derive the instantaneous signal-to-interference-and-noise ratio (SINR) and then obtain the OP expression for each user in a closed form. The derived expression for OP is general and includes special cases such as Nakagami-m, Weibull, Gamma, Rayleigh, and Exponential distributions. This ?-? expression helps quantify the improvement of the OP performance. In order to improve the OP performance, multiple antennas are included for the users, and then receive antenna selection (RAS) scheme is employed. The theoretical OP expressions are verified via Monte Carlo simulations.
