A Combined Filter for Synchronous Detection in Underwater Acoustic Mobile Communication System
Xibei Gongye Daxue Xuebao, 2020 A scale-stretching combined filter is proposed for underwater acoustic mobile communication receivers. The combined filter consists of the sum of signals with different time stretching and shifting.

Matched-Filter Detection of Mode-Locked Laser Signals [PDF]
, 1973 The passive Fabry-Perot cavity is shown to be a good practical approach to the match-filter optimization for the sensitive detection of mode-locked laser signals. Doppler measurements of relative motion over a wide range of velocities are possible simply

Joint Optimization of Signal Waveforms and Filters for Long-Range MIMO Radars
IEEE Access, 2022 This paper describes a new cyclic algorithm for minimization of signal sidelobes and crosstalk in multiple-input multiple-output (MIMO) radar. The designed algorithm, called SWAP by the authors, is suitable mainly for long-range radars, such as ground ...

A pseudo-matched filter for chaos
, 2012 A matched filter maximizes the signal-to-noise ratio of a signal. In the recent work of Corron et al. [Chaos 20, 023123 (2010)], a matched filter is derived for the chaotic waveforms produced by a piecewise-linear system.

Outlier Resistant Rapid Adaptive Matched Filter
IEEE AccessThis paper presents an outlier-resistant implementation of the Doppler Domain Localized (DDL) Adaptive Matched Filter (AMF). Outliers, defined as training data vectors closely correlated with the test cell’s vector, can severely degrade adaptive ...

A dToF Ranging Sensor with Accurate Photon Detector Measurements for LiDAR Applications
Sensors, 2023 Direct time-of-flight (dToF) ranging sensors based on single-photon avalanche diodes (SPADs) have been used as a prominent depth-sensing devices. Time-to-digital converters (TDCs) and histogram builders have become the standard for dToF sensors. However,
