Abstract :
Peak-constrained least-squares (PCLS) optimization is a relatively new approach to solving digital filter design problems. Motivations for the PCLS optimality criterion are discussed previously. However, the PCLS examples and design methods proposed by Adams (1991) and Adams, Sullivan and Hashemi (1993) are focused on real symmetric FIR digital filters and windows. In this paper we extend the PCLS approach to the design of complex FIR digital filters and windows.
