The discrete time–frequency matched filter should replicate the continuous time–frequency
matched filter, but the methods differ. To avoid aliasing, the discrete method transforms the …

Matched filter (MF) is well known to yield the highest output signal-to-noise ratio (SNR)
among all possible linear time-invariant filters. However, the matched filter takes on complex …

An efficient realization of a low delay filter-bank will be proposed, which can be regarded as
a filter-bank used as equalizer with either fixed or time-varying spectral gain factors. The …

A matched filter is viewed as a cascade of a spectral-phase matched filter and a spectral-
amplitude shading filter. The former provides the peak output in time, and the latter …

In this article, we describe an obscure but simple and powerful method for designing a
digital filter that approximates an arbitrary magnitude and phase response. Called frequency …

A fast-matched filter algorithm in time domain is presented to correlate signals for optimal
detection of signals in noise, to extract ranging measurements, for synchronisation, and so …

Minimax or robust filters which optimize worst-case performance have been considered
previously for matched and Wiener filtering. In this paper we show how similar ideas can be …

A new approach to the problem of time-variant filtering is presented. This approach is based
upon the generation of the mixed time-frequency representation (MTFR) of a signal …

In this letter, a sinusoidal time-frequency distribution based filtering (STFD-F) algorithm is
proposed and analysed for estimating mono-component stationary sinusoidal signals …

The concept of rotation in the joint time-frequency plane can be exploited in order to
generalize classical Fourier-based operations. It is known that filtering in rotated time …
