| 摘 要： | 针对结构健康无线传感器网络监测系统中,需要对节点数据进行预处理问题,采用FPGA（field-programmable gate array）为硬件平台,设计了FIR（finite impulse response）数字滤波器,对节点的数据进行数字滤波处理.设计中利用MATLAB/Simulink、DSP Builder软件对数字滤波器进行建模、滤波系数计算、系统模型仿真和生成相应的VHDL工程文件;利用Quartus-II软件对工程文件进行综合、编译和调试,并且生成相应的底层原理图模块.通过对1 kHz和4 kHz的两个正弦波混合信号进行仿真滤波表明,4 kHz的高频干扰信号被有效地滤除,实现了FIR滤波器的性能.将生成的VHDL代码下载到FPGA中,实现了基于FPGA的FIR滤波器设计.
