520			_aThe evolution of future generations of mobile wireless communication systems has intensified the demand for higher data rates, reduced latency, and improved spectral efficiency. Non-orthogonal multiple access (NOMA) has emerged as a groundbreaking solution to meet these demands. Which enables the sharing of time-frequency resources and utilizes successive interference cancellation (SIC) to mitigate interference among multiple users. As well, cooperative communications based on relays offer dependable connectivity and extend system coverage. While multiple inputs multiple outputs (MIMO) technology significantly contributes to the evolution of NOMA systems. The integration of MIMO using antenna selection (AS) schemes in NOMA enhances overall performance, decreases complexity and power consumption, which is a novel and appealing approach in this context. Within this thesis, we evaluate the effectiveness of implementing multi-antenna techniques within NOMA networks under realistic conditions, considering practical challenges such as SIC error, channel estimation error (CEE), and feedback delay error. The analysis begins with an examination of the singleinput single-output (SISO) system in Downlink and Uplink NOMA networks, deriving mathematical expressions for ergodic capacity (EC), outage probability (OP), and bit error rate (BER). Subsequently, we investigate the MIMO-NOMA network, utilizing the joint transmit and receive antenna selection (JTRAS) protocol, and derive the expression for EC under realistic conditions. Later, we assess the performance of the Downlink cooperative NOMA network employing a relay selection strategy, incorporating both best relay selection (BRS) and partial relay selection (PRS) through the implementation of a transmit antenna selection (TAS) protocol. Finally, the thesis concludes with a comprehensive analysis of the results, highlighting challenges while offering valuable insights that can significantly influence future research in the field.
