FIR to FIR Model Reduction with Linear Group Delay in Passband by SDP Optimization

Journal of Electrical and Computer Engineering, 2020
Filter model reduction is an important optimization method in digital signal processing. A method of FIR to FIR model reduction using SDP optimization is proposed in this paper. At first, we use SDP to design an original FIR filter.
