Hybrid DDoS Detection Framework Using Matching Pursuit Algorithm

IEEE Access, 2020
Although a considerable amount of research has been done on DDoS attacks, it still poses a severe threat to many businesses and internet service providers. DDoS attacks commonly generate a high amount of network traffic.

Efficient Distributed Multi-Task Schemes for mmWave MIMO Channel Estimation

IEEE Access, 2022
In this study, the problem of sparse channel estimation is investigated with the employment of a fully distributed approach. We exploit the spatially joint sparsity structure of the involved channels to formulate the channel estimation problem in the ...

A New Sparse Adaptive Channel Estimation Method Based on Compressive Sensing for FBMC/OQAM Transmission Network

Sensors, 2016
The conventional channel estimation methods based on a preamble for filter bank multicarrier with offset quadrature amplitude modulation (FBMC/OQAM) systems in mobile-to-mobile sensor networks are inefficient.

Block Multipath Matching Pursuit

, 2023
In this paper, we propose a new reconstruction algorithm called Block Multipath Matching pursuit (BMMP), which is an extension of multipath matching pursuit (MMP) in block compressed sensing. Then the reconstruction condition of BMMP based on restricted isometric property (RIP) is established. In addition, we also provides a guarantee of reconstruction

Sparse approximation of multivariate functions from small datasets via weighted orthogonal matching pursuit

, 2019
We show the potential of greedy recovery strategies for the sparse approximation of multivariate functions from a small dataset of pointwise evaluations by considering an extension of the orthogonal matching pursuit to the setting of weighted sparsity ...

One-Bit Compressed Sensing by Greedy Algorithms [PDF]

, 2013
Sign truncated matching pursuit (STrMP) algorithm is presented in this paper. STrMP is a new greedy algorithm for the recovery of sparse signals from the sign measurement, which combines the principle of consistent reconstruction with orthogonal matching

Target Localization Algorithm of Wireless Sensor Network Based on Fast Orthogonal Matching Pursuit in

Xibei Gongye Daxue Xuebao, 2020
Efficient localization of multiple targets is one of the basic technical problems in wireless sensor networks (WSN). The traditional sparse representation method based on greedy class is not efficient in multi-target positioning.

Optimization of Matching Pursuit Encoder Based on Analytical Approximation of Matching Pursuit Distortion [PDF]

2006 IEEE International Conference on Multimedia and Expo, 2006
Distortion of matching pursuit is calculated in terms of matching pursuit encoder parameters for uniformly distributed signals and dictionaries. Then, the MP encoder is optimized using the analytically derived approximation for MP distortion. Our simulation results show that this optimized MP encoder exhibits optimum performance for nonuniform signal ...
