Coexistence Demonstration and Wavelength Dependency Analysis of S-Band CV-QKD Signal with Fully Loaded C+L-Band DWDM Signals [PDF]

open access: yesEntropy
We demonstrated the coexistence of an S-band CV-QKD signal with fully loaded C+L-band classical signals for the first time. The secret key rate of the S-band QKD system was 986 kbps with the C+L-band WDM signals transmitted through a 20 km G.654.E fiber ...

Algebra of L-Banded Matrices

open access: yesIEEE Access, 2023
Convergence is a crucial issue in iterative algorithms. Damping is commonly employed to ensure the convergence of iterative algorithms. The conventional ways of damping are scalar-wise, and either heuristic or empirical. Recently, an analytically optimized vector damping was proposed for memory message-passing (iterative) algorithms.

A Comprehensive Systematic Literature Review on Intrusion Detection Systems

open access: yesIEEE Access, 2021
Effectively detecting intrusions in the computer networks still remains problematic. This is because cyber attackers are changing packet contents to disguise the intrusion detection system (IDS) recently.

Pocketqube L-Band RFI Detection Payload

open access: yesIGARSS 2023 - 2023 IEEE International Geoscience and Remote Sensing Symposium, 2023
In the last decades, the number of wireless devices has notably increased, and improper RF filtering has resulted in an increase in Radio Frequency Interference (RFI). At L-band this is due to a plethora of reasons: from VHF/UHF harmonics, higher frequency band (e.g. WiFi boosters) emissions, or even intentional RFI created by Personal Privacy Devices (

Design of 960~1 400 MHz broadband power amplifier

open access: yesDianzi Jishu Yingyong, 2023
Based on laterally diffused metal-oxide-semiconductor (LDMOS) devices, a broadband RF power amplifier for L-band was developed. The amplifier is composed of two stages of amplification and cascade connection. In order to achieve broadband and good output

Adaptation of Amorpha fruticosa to different habitats is enabled by photosynthetic apparatus plasticity

open access: yesPhotosynthetica, 2021
The rapid growth and spreading of invasive plant species could be related to their efficient photosynthesis performance. We analysed and compared photosynthetic efficiency of invasive indigo bush (Amorpha fruticosa L.) and noninvasive native Quercus ...
