摘　　要：提出了数字波束形成的方法,该方法是利用FPGA进行空域滤波,通过DSP浮点运算,高效地实现权值估计,避免高位加法进位影响计算速度。同时使用软件方式完成自适应算法的更新,增强了系统灵活性,是一种简便易行的实现方法。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.
