基于自适应FIR滤波器的抗干扰ASIC设计

The Anti Jamming ASIC Based on Adapt FIR Filter

本文简要介绍了自适应滤波器的原理,并以窄带抗干扰系统中的LMS算法自适应FIR滤波器为研究对象,采用MATLAB软件进行仿真,结果表明该滤波器针对窄带干扰时,相对于传统方法有着更好的抑制效果。另外,在ASIC实现时,可以在最小的面积上获得所需的速度。

This paper first introduces the basic principle of adapt filter. The adapt filter uses the LMS algorithm to anti narrowband jamming. Based on the Matlab simulation, the results show that this filter has the better restrain effect than the traditional method. In addition, in the ASIC design,can gain the need speed on the least area.
