The application of smart antenna in radio communication technology

Smart antenna has become one of the important technologies in the field of communication. The smart antenna is the combination of adaptive antenna technology, digital signal processing technology and software radio technology, the smart antenna can also improve the system capacity and communication quality by adjusting its own parameters, and can delete or suppress the interference signal. The performance of the communication system can be improved by increasing the antenna gain and spectrum utilization through the application of smart antenna. In this paper, the basic structure of smart antenna is described, the advantages of smart antenna are compared, the development trend of smart antenna technology is analyzed, and the future of smart antenna is prospected.
