Abstract:

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.
