In the era of next-generation wireless communication, the demand for enhanced data rates, reliability, and Quality of Service (QoS) has catalyzed the adoption of Multi-Input Multi-Output (MIMO) systems. This paper presents a comprehensive performance analysis of MIMO systems using various modulation schemes over Additive White Gaussian Noise (AWGN) and Rician fading channels. Furthermore, it integrates a deep learning-based optimization framework to enhance QoS in multi-user MIMO environments. Simulation results demonstrate how different modulation techniques BPSK, QPSK, 16-QAM, and 64-QAM perform under both AWGN and Rician channels, and how neural networks can predict optimal resource allocation to minimize Bit Error Rate (BER) and latency. The work offers valuable insights into modulation performance and deep learning-driven QoS optimization in modern wireless networks.
