我们考虑的问题,设计一个稀疏的FIR滤波器,并表明,它可以被转换成一个问题,确定一个稀疏的线性方程组的解决方案。以前提出的FIR滤波器的设计算法利用智能搜索所有可能的稀疏滤波器的结构。我们提出了一种新的滤波器设计方法的基础上找到一个稀疏的线性系统的解决方案,一个更简单的算法。仿真实验表明,显着的改进,经典的非稀疏方法。
We consider the problem of designing a sparse FIR filter and show that it can be cast into a problem of determining a sparse solution of a linear system of equations. Previously proposed design algorithms for FIR filter utilize an intelligent search over all possible structures for sparse filter. We propose a new filter design method based on a simpler algorithm for finding a sparse solution of the linear system. Simulation experiments show significant improvements over classical nonsparse methods.
