Implementation and optimisation of pulse compression algorithm on open CL-based FPGA

open access: yesThe Journal of Engineering, 2019
As Moore's law meets bottlenecks, the demand for heterogeneous parallel processing systems is increasing. Field-programmable gate arrays (FPGAs) are becoming more efficient acceleration devices due to their powerful processing performance, and the CPU ...

Power-Bandwidth Tradeoff for Ultra-Low Power MFSK and G-MFSK Systems

open access: yesIEEE Access, 2023
In one of our previous papers, we designed an ultra-low power non-coherent MFSK system using 2-pole bandpass filters to replace matched filters for detection and showed the performance loss between our proposed system and the optimal MFSK system using ...

Some Good Reasons to Use Matched Filters for the Detection of Point Sources in CMB Maps

open access: yes, 2003
In this draft we comment on the results concerning the performances of matched filters, scale adaptive filters and Mexican hat wavelet that recently appeared in literature in the context of point source detection in Cosmic Microwave Background maps.

High-Order Dual-Port Quasi-Absorptive Microstrip Coupled-Line Bandpass Filters [PDF]

open access: yes, 2020
In this article, we present the first demonstration of distributed and symmetrical all-band quasi-absorptive filters that can be designed to arbitrarily high orders.

On Optimal Detection of Point Sources in CMB Maps

open access: yes, 2002
Point-source contamination in high-precision Cosmic Microwave Background (CMB) maps severely affects the precision of cosmological parameter estimates. Among the methods that have been proposed for source detection, wavelet techniques based on ``optimal''

Retinal Vessels Segmentation Techniques and Algorithms: A Survey

open access: yesApplied Sciences, 2018
Retinal vessels identification and localization aim to separate the different retinal vasculature structure tissues, either wide or narrow ones, from the fundus image background and other retinal anatomical structures such as optic disc, macula, and ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Sparse direction of arrival estimation of co-prime MIMO radar using sparse aperture completion

open access: yesThe Journal of Engineering, 2019
In this study, the authors consider the problem of direction of arrival (DOA) estimation in compressive sensing multiple-input and multiple-output (CS-MIMO) radars with co-prime receive arrays. A sparse aperture completion scheme is proposed to fill the ‘

IIR Adaptive Filters for Detection of Gravitational Waves from Coalescing Binaries

open access: yes, 2004
In this paper we propose a new strategy for gravitational waves detection from coalescing binaries, using IIR Adaptive Line Enhancer (ALE) filters. This strategy is a classical hierarchical strategy in which the ALE filters have the role of triggers ...
