为了提高可重构频罩滤波器的设计结果，提出了一种基于二阶锥优化的改进设计方法。不同于传统的将所有子滤波器分开设计的方法，该方法将所有期望的设计模式纳入到设计目标中来联合设计所有子滤波器。首先，单独设计所有子滤波器以获得一个初始结果；然后，迭代求解一个二阶锥优化问题，以更新初始结果。通过一个设计实例来验证所提出算法的有效性。仿真结果表明，相比于传统的设计方法，将所有子滤波器联合设计能够显著降低minimax准则的设计误差。

In order to improve the design results for the reconfigurable frequency response masking FRM filters an improved design method based on second-order cone programming SOCP is proposed.Unlike traditional methods that separately design the proposed method takes all the desired designing modes into consideration when designing all the subfilters. First an initial solution is obtained by separately designing the subfilters and then the initial solution is updated by iteratively solving a SOCP problem. The proposed method is evaluated on a design example and simulation results demonstrate that jointly designing all the subfilters can obtain significantly lower minimax approximation errors compared to the conventional design method.
