Abstract
With the rapid development of wireless communication technology, the demand for data transmission is growing exponentially, and the traditional single antenna system is gradually difficult to meet the requirements of increasingly complex communication scenarios. To this end, this study focuses on the application of multi-antenna technology in modern communication systems, aiming to solve the current communication bottleneck problem by improving the spectral efficiency and system capacity. The study uses theoretical analysis and simulation verification to explore the working principle of multi-input and multi-output (MIMO) technology and its performance in different communication environments. Specifically, through the construction of the channel model and the design of the optimization algorithm, a low-complexity precoding scheme suitable for the large-scale MIMO system is proposed, which effectively reduces the computational overhead and improves the energy efficiency. In addition, the study also evaluated the potential of multi-antenna technology in 5G and future 6G networks, especially in the field of millimeter-wave communication and beamforming.
