摘要
提出了一种设计稀疏FIR数字滤波器的快速算法。该算法是在文献[19]所提算法的基础上进行了适当的改进。所提算法有效解决了L1-L2优化问题,具有很快的收敛性,并且新算法解决了权衡参数的选取问题。应用该算法成功设计了一维与二维的FIR稀疏数字滤波器,并与非稀疏情况下的设计进行了比较,仿真结果也表明本文所提算法的有效性。
A new efficient algorithm for designing sparse FIR digital filters is derived in this paper This new algorithm is an improved version of the one described in [ 19 ] o The L1 - L2 minimization and the trade - off for parameter selection are efficiently solved by the proposed algorithmo 1D and 2D FIR sparse filters are designed using the proposed algorithm and compared with non -sparse fiherso The simulations demonstrate the proposed algorithm is very efficient.
