| 摘 要： | 在自适应滤波器的设计中，滤波阶数增加时，保持滤波器的吞吐量成为了设计的难点。文章根据最小均方（LMS）算法自适应FIR数字滤波器的基本原理，介绍了一种改进型分布式算法DA自适应FIR数字滤波器在FPGA中的设计方法。设计在QuartusⅡ中编译、仿真、综合后下载到Stratix FPGA中较好地解决了滤波器阶数增加与吞吐量之间的关系。

| Abstract: | When increase tap of filtering,keeping throughput of filers has become difficulty of design in designing adaptive digital filter.In design of FPGA,the method of adaptive digital filter of improving distributed arithmetic based on theory of adaptive digital filter of Least Mean Square(LMS) was introduced in the paper.Design result was proved availability in the throughput by compile and emulation and synthesis and load to Stratix FPGA in the Quartus II. |
