Improvement of Noise Uncertainty and Signal-To-Noise Ratio Wall in Spectrum Sensing Based on Optimal Stochastic Resonance

Sensors, 2019
Noise uncertainty and signal-to-noise ratio (SNR) wall are two very serious problems in spectrum sensing of cognitive radio (CR) networks, which restrict the applications of some conventional spectrum sensing methods especially under low SNR ...

Location Based Encryption

, 2019
We first propose a 2D Location Based Encryption (LBE) scheme, where the setting includes a geography center system and the 2D triangle area including the set of locations. A user joining in the system is provided with a pre-arranged key, which belongs to her/his location. If the user’s location is belonging to this area, he/she can decrypt the message.

Memory-Saving Implementation of High-Speed Privacy Amplification Algorithm for Continuous-Variable Quantum Key Distribution

IEEE Photonics Journal, 2018
Privacy amplification is an indispensable procedure to share secure secret key between legitimate parties in quantum key distribution (QKD) because a portion of bits are still leaked to eavesdropper Eve after the secret reconciliation. Here, we propose a

Unorganized fibrocartilage and osseous proliferation after bone marrow stimulation for an osteochondral lesion of the talus

Journal of Cartilage & Joint Preservation, 2021
Introduction: Bone marrow stimulation (BMS) is the most commonly used treatment for an osteochondral lesion of the talus (OLT). BMS can fail, however, and may require revision surgery.
