【 摘 要 】

References(9)In this paper, the design and implementation of a smart antenna system for ultra high frequency (UHF) vehicle-mounted communication is proposed. The project adopts the improved multiple signal classification (MUSIC) algorithm which realized in field programmable gate array (FPGA), and implements robust superdirective beamforming algorithm based on digital signal processor (DSP). They contribute to achieving super-resolution target direction-finding and gaining output beam signals. This solution has greatly improved the signal interference noise ratio (SINR) and the signal's intensity in communication. The experimental results indicate that the system works smoothly with a rapid response and a strong stability, and satisfies the demand of engineering application.
