Design of frequency-response-masking FIR filters using SOCP with coefficient sensitivity constraint

Abstract

Abstract-In this paper, we present an analysis on the coefficient sensitivity (CS) of a second-order cone programming (SOCP) based method for the design of FRM filters and show that the method is guaranteed to produce FRM filters with low CS as long as the CS of the initial FRM filter is low. Moreover, we present an enhanced SOCP-based design method that incorporates a constraint on the CS measure S
