说明： 基于FPGA的数字下变频器（DDC）的设计,将采样得到的高速率信号变成低速率基带信号，以便进行下一步的信号处理。由NCO、数字混频器、低通滤波器和抽取滤波器四个模块组成。采用自编的加法树乘法器，提高乘法运算效率。
(Design based on FPGA digital downconverter (DDC), the high-speed signal will be sampled baseband signal into a low rate for the next step in the signal processing. Is composed of four modules of the NCO, the digital mixer, the low pass filter and a decimation filter. Adder tree multiplier using self efficient multiplication.)
