evolFIR: Evolving redundancy-free FIR structures

In this paper, the designs of fractional delay filter, Nyquist filter, lowpass filter and diamond-shaped filter are presented. First, the relation between Nyquist filter and fractional delay filter is investigated such that the design tools of one ...

This paper proposes a pair of new structures for implementing low-complexity odd-order and even-order variable fractional-delay (VFD) FIR filters using hybrid structures with both even-order and odd-order subfilters. For odd-order VFD filter design, the ...

• A Kalman filter framework for finding the optimal response of digital IIR filters is proposed.

Recently, a unified framework was proposed for forward-backward filtering and penalized least-squares optimization. It was shown that forward-backward filtering can be presented as instances of penalized least-squares optimization. In ...
