Adaptive Processing With Signal Contaminated Training Samples [PDF]
IEEE Transactions on Signal Processing, 2013 We consider the adaptive beamforming or adaptive detection problem in the case of signal contaminated training samples, i.e., when the latter may contain a signal-like component. Since this results in a significant degradation of the signal to interference and noise ratio at the output of the adaptive filter, we investigate a scheme to jointly detect ...

Highlighting Problems Occurring in Analysis of Critical Sampling of Cosinusoidal Signal [PDF]
TransNav, 2020 When the sampling of an analog signal uses the sampling rate equal to exactly twice the value of a maximal frequency occurring in the signal spectrum, it is called a critical one.

Adaptive importance sampling in signal processing [PDF]
Digital Signal Processing, 2015 In Bayesian signal processing, all the information about the unknowns of interest is contained in their posterior distributions. The unknowns can be parameters of a model, or a model and its parameters. In many important problems, these distributions are impossible to obtain in analytical form.

Real-Time Eye Diagram Monitoring for Optical Signals Based on Optical Sampling
Applied Sciences, 2023 A real-time eye diagram monitoring method for optical signals is proposed and experimentally demonstrated based on optical sampling. In the system, the optical signals under test are directly sampled by an optical sampling pulse train with a narrow pulse

Optical signal processing via two-photon absorption in a semiconductor microcavity for the next generation of high-speed optical communications network [PDF]
, 2006 Due to the introduction of new broadband services, individual line data rates are expected to exceed 100 Gb/s in the near future. To operate at these high speeds, new optical signal processing techniques will have to be developed.

Detecting Network Intrusions Using Signal Processing with Query-Based Sampling Filter
EURASIP Journal on Advances in Signal Processing, 2008 This paper presents a novel approach for training a network intrusion detection system based on a query-based sampling (QBS) filter. The proposed QBS filter applies the concepts of data quantization to signal processing in order to develop a novel ...

EURASIP Journal on Advances in Signal Processing, 2023 Sampling and reconstruction play a critical role in signal processing. The non-ideal sampling conditions motivate the development of the sampling theory. In this paper, associated with multiple non-ideal conditions, we discuss the nonuniform sampling and
