WiMAX technology has become a pivotal solution for high-speed wireless broadband access. This research paper investigates the performance of MIMO-OFDM systems utilizing various modulation schemes, including BPSK, QPSK, 8-QAM, and 16-PSK. The study primarily focuses on the Symbol Error Rate (SER) in relation to the Signal-to-Noise Ratio (SNR). By analysing SER versus SNR, the paper provides insights into the robustness and efficiency of each modulation scheme under different SNR conditions. The results are essential for enhancing the performance and reliability of WiMAX networks, offering valuable guidance for network optimization and deployment strategies.
