为了减少自适应滤波器的计算复杂度以及缩短设计周期,对自适应滤波器结构进行合理的划分,依据收敛性和计算复杂度两个主要性能指标,在Matlab的Simulink中的DSP Bulider平台下,搭建了一个自适应滤波器模型,该设计能够灵活地改变滤波器的系数,从而灵活地改变自适应滤波器的收敛性,根据实际的需要设计滤波器,易于修改和调试。同时,Simulink的强大的图形化界面,辅助简化设计流程,提高了设计效率。
In order to reduce the computational complexity and shorten the design cycle of the adaptive filter, the structure of the adaptive filter is reasonably divided. Based on the two main performance indexes of convergence and computational complexity, under the DSP Bulider platform in Matlab Simulink, An adaptive filter model is built, which can flexibly change the coefficients of the filter so as to flexibly change the convergence of the adaptive filter. The filter is designed according to actual needs and is easy to modify and debug. At the same time, Simulink’s powerful graphical interface helps simplify the design process and improve design efficiency.
