Abstract
The rapid development of wireless communication technology makes multi-antenna technology the key to improve the system performance. Through multi-antenna sending and receiving signals, the technology significantly improves the spectrum efficiency, transmission rate, enhances the signal quality and stability, and expands the coverage and capacity of the system. The three major features of multi-antenna technology include: spatial multiplexing and beamforming technology improve spectrum efficiency and transmission rate to meet the requirements of high-speed data transmission; diversity technology and array gain improve signal quality and stability, reduce code error rate; significantly increase system coverage and capacity, and support the expansion and optimization of wireless communication network. Multi-antenna technology has a wide application value in wireless communication, which can significantly improve the data transmission rate, solve the problem of signal blind area, inhibit multi-path interference, improve the signal anti-interference ability, and ensure the reliable operation of the network. However, multi-antenna technologies also faces challenges such as insufficient hardware resources, complex signal processing, interantenna interference and deployment difficulties. To address these challenges, strategies such as rational allocation of hardware resources, using advanced technology to process signals, optimizing the antenna layout, and developing detailed implementation plans are required.
