Efficient subband adaptive filtering with oversampled GDFT filter banks [PDF]

open access: yes, 1997
This paper addresses the numerical efficiency of adaptive filtering implemented in subbands. Our approach first focuses on oversampled GDFT (generalized DFT) filter banks and their potential benefits over other possible subband decompositions.

A Coq Formalization of Digital Filters [PDF]

open access: yes, 2018
Digital filters are small iterative algorithms, used as basic bricks in signal processing (filters) and control theory (controllers). They receive as input a stream of values, and output another stream of values, computed from their internal state and from the previous inputs.

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

open access: yesJournal 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.
