Implementation and Formation of Smart Antenna Digital Beam Based on FPGA

A method of digital beam formation of smart antenna system is introduced.By the method,FPGA is utilized for conducting the spatial filter,weight estimation is realized through the float point calculation of DSP,thus preventing High order addition carry from lowering the calculation speed.Simultaneously the flexibility of system is improved by updating the adaptive algorithm in the software way.And,the method is easy to implement in practice.
