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 result of the reconfigurable cover filter, an improved design method based on the second-order cone optimization is proposed.Compared with the traditional method of designing all the sub-filters separately, this method incorporates all the desired design patterns To design the target to jointly design all the subfilters.Firstly, all the subfilters are designed individually to obtain an initial result.And then, a second order cone optimization problem is iteratively solved to update the initial result.According to a design example to verify the proposed The simulation results show that compared with the traditional design method, all sub-filter joint design can significantly reduce the design error of minimax criterion.
