Abstract

The rapid development of wireless communication technology has imposed higher requirements on the performance of communication systems, leading to the emergence of beamforming technology as a key technique to enhance the performance of wireless communication systems. This study focuses on beamforming technology and its optimization in wireless communications, aiming to explore its application potential and improvement space in complex electromagnetic environments. By analyzing the principles of existing beamforming technologies and integrating the requirements of modern communication scenarios, an intelligent algorithm-based beamforming optimization scheme is proposed. This scheme employs deep learning algorithms for channel state prediction and establishes a multi-ob jective optimization model to maximize energy efficiency while ensuring communication quality. Simulation results demonstrate that the proposed optimization scheme significantly improves spectral efficiency and coverage in various complex environments, achieving approximately a 30% increase in data transmission rates and a 20% reduction in bit error rates compared to traditional methods. Furthermore, this research explores beamforming technology in large-scale antenna array scenarios, innovatively introducing an adaptive beam adjustment mechanism that enables dynamic beam direction adjustments according to real-time environmental changes, thereby enhancing system flexibility and robustness and providing new insights and technical support for the future development of wireless communication systems.
