Abstract

In this work a new technique for design of narrow-band and wide-band linear-phase finite-length impulse response (FIR) frequency-response masking based filters is introduced. The technique is based on a sparse FIR filter design method for both the model (bandedge shaping) filter as well as the masking filter using mixed integer linear programming optimization. The proposed technique shows promising results for realization of efficient low arithmetic complexity structures.
