TECHNICAL ANALYSIS OF MASSIVE MIMO KEY TECHNOLOGY IN 5G

Abstract

The advent of the fifth-generation mobile communication network (5G) has sparked widespread interest and significant research efforts from global corporations, research organizations, and academic institutions. Among the key technologies envisioned for future 5G networks, massive Multiple Input Multiple Output (MIMO) technology stands out for its potential to enhance spectrum utilization and communication channel capacity. This paper provides a comprehensive analysis of the standardization process for MIMO technology and highlights the technical advantages of massive MIMO. It explores various application scenarios and examines channel measurement and modeling from a detailed perspective. Furthermore, the paper delves into the intricacies of channel estimation, precoding, and signal detection technologies within massive MIMO systems, concluding with a comprehensive summary.
