Journal of Marine Science and Engineering, 2021 In this paper, we use two methods to research the propagation characteristics of a Hypergeometric-Gaussian (HyGG) vortex beam under oceanic turbulence. One is numerical calculation based on the Rytov approximation theory, where the theoretical detection ...

Ghost edge detection based on HED network
Frontiers of Optoelectronics, 2022 In this paper, we present an edge detection scheme based on ghost imaging (GI) with a holistically-nested neural network. The so-called holistically-nested edge detection (HED) network is adopted to combine the fully convolutional neural network (CNN ...

Capturing the amplitude and phase profile of the vortex beam based on coherent detection
Frontiers in Physics, 2022 In this study, we propose a scheme to capture the amplitude and phase profile of the orbital angular momentum (OAM) beam based on coherent detection. In the scheme, the OAM beam to be measured is interfered with a local plain wave which is prepared at ...

Performance Comparison of Impedance-Based Fault Location Methods for Transmission Line
International Journal of Electrical and Electronic Engineering & Telecommunications, 2022 Electric transmission lines play a very essential role in transmitting power energy from generation centers to consumption regions. They can be exposed to fault occurrences due to various reasons, such as lightning strikes, malfunction of components, and

Sending-or-Not-Sending Twin-Field Quantum Key Distribution with a Passive Decoy-State Method
Entropy, 2022 Twin-field quantum key distribution (TF-QKD) has attracted considerable attention because it can exceed the basic rate-distance limit without quantum repeaters.

Error correction in data storage systems using polar codes
IET Communications, 2021 This paper investigates error correction in two‐dimensional (2‐D) intersymbol interference (ISI) channels using polar codes. 2‐D channels offer high data storage capacity compared to traditional one‐dimensional (1‐D) channels but suffer from greater ISI ...

Network Coding Datagram Protocol for TCP/IP Networks
IEEE Access, 2023 In this article, a new multicast protocol is introduced at the session layer, which is based on network coding and is called the Network Coding Datagram Protocol (NCDP). The NCDP protocol is specifically designed for content delivery systems that utilize
