我们给出了插值型和频响屏蔽型FIRfi的极大极小设计的一种统一方法，这是一类著名的计算量大的数字fifi。这些fi的高度非凸极大极小设计是通过使用凸凹法联合优化所涉及的子fi来实现的。我们解释了为什么CCP非常适合于手头的设计问题，并给出了两个设计实例来展示它的性能。
—We present a unified approach to minimax design of interpolated and frequency-response-masking FIR filters which are well-known classes of computationally efficient digital filter. The highly nonconvex minimax designs of these filters are carried out by jointly optimizing the subfilters involved using a convex-concave procedure (CCP). We explain why CCP is well-suited for the design problems at hand and present two design instances to demonstrate its performance.
