Proceedings ArticleDOI
Anomaly detection in IP networks based on randomized subspace methods
TL;DR: Novel randomized subspace methods to detect anomalies in Internet Protocol networks by performing a normal-plus-anomalous matrix decomposition aided by the randomized sampling scheme and subsequently detecting traffic anomalies in the anomalous subspace using a statistical test.
Proceedings ArticleDOI
Knowledge-aided STAP algorithm using convex combination of inverse covariance matrices for heterogenous clutter
TL;DR: This paper develops a KA-STAP algorithm to estimate the inverse interference covariance matrix rather than the covariANCE matrix itself, by combining the inverse of the covariance known a priori, R0-1, and the inverse sample covariance Matrix estimate R̂-1.
Journal ArticleDOI
List-Based OMP and an Enhanced Model for DOA Estimation with Non-Uniform Arrays
Journal ArticleDOI
Design of Compressed Sensing System With Probability-Based Prior Information
TL;DR: The design of a sensing matrix along with a sparse recovery algorithm by utilizing the probability-based prior information for compressed sensing systems and a probability-driven orthogonal matching pursuit algorithm that improves the accuracy of the recovery are proposed.
Journal ArticleDOI
Gradient-based algorithm for designing sensing matrix considering real mutual coherence for compressed sensing systems
TL;DR: A novel strategy of the sensing matrix design is proposed by using a gradient-based method, in which the measure of real mutual coherence for the equivalent dictionary is considered, and a minimised objective function based on alternating minimisation is developed through searching the target Gram within a set of relaxed equiangular tight frames.
