摘要
讨论了自适应滤波去噪原理,采用LMS算法设计了自适应去噪滤波器,分析了MAT-LAB/SIMULINK中DSP Builder模块库在FPGA中的设计优点,最后应用DSP Builder模块库对自适应滤波器进行仿真。为自适应滤波器硬件实现提供了实验依据。
The article firstly designed an adaptive model of removing noise based on the theory of LMS adaptive algorithm. Then it analysed the advantage of module library of DSP Builder in MATLAB/SIMUHNK in FPGA design. In the end, a method that how to simulate the model in DSP Builder was provided. It described a simple way which can completely implement complex adaptive filters in FPGA chip.
