| 摘 要： | 提出了一种任意频率响应FIR滤波器的快速精确设计方法。采用使设计出的FIR滤波器频率响应与期望频率响应之间误差的加权l2范数最小的准则,将问题转化成二阶锥约束优化的问题,然后利用内点方法来求解滤波器的优化系数。通过仿真结果发现,与LMS自适应滤波器设计方法相比较,利用本文方法设计的任意频率响应FIR滤波器精度更高。

| Abstract: | The algorithms for the design of Finite-impulse response(FIR) filters with arbitrary magnitude and phase responses are developed using second-order cone programming.The designed filters can be computed by minimizing the weighted l2-norm of frequency domain response error between the designed filter and the prescribed one respectively.This design problem can be formulated as the so-called second-order cone(SOC) programming and solved efficiently using the well-established interior point method.Compared with the LMS adaptive filter design method,the simulation results show the effectiveness of the method developed in this paper. |
