基于DSP Builder的自适应滤波器的模型搭建

DSP Builder-based Model of Adaptive Digital Filter

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 of adaptive filter and shorten the design cycle,the adaptive filter structure is reasonably divided.Based on the convergence and computational complexity of two main performance indexes and with DSP Bulider software,the model of adaptive filter is built up.This design could flexibly change the coefficients and thus the convergence of the adaptive filter.The filter design based on actual demand is easy to easy in modification and debug.Meanwhile,simulink,with powerful graphical interface,could greatly improve the design efficiency.
