An Adaptive Simplified Travelling Wave‐Based Fault Detection, Classification and Location Estimation Strategy for Series Compensated Transmission Lines

IET Smart Grid, Volume 8, Issue 1, January/December 2025.
This paper proposes an integrated model for fault detection, classification, and location in power transmission systems using voltage signals from a single terminal of a series‐compensated line. Simulations show the model achieves 100% accuracy for fault detection, classification and faulty segment identification, and 99.79% accuracy for fault location

Blind Recognition Algorithm of Convolutional Code via Convolutional Neural Network

International Journal of Intelligent Systems, Volume 2025, Issue 1, 2025.
Pointing at the vexed question of blind recognition in the convolutional code class, this paper proposes a convolutional code blind identification method via convolutional neural networks (CNNs). First, this algorithm uses the traditional method to generate different convolutional codes, and the feature extraction algorithm adopts the theorem of Euclid’

Securing Communication Channels: An Advanced Steganography Approach With Orthogonal Frequency Division Multiplexing (OFDM)

Journal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.
Orthogonal frequency division multiplexing (OFDM) is a widely used modern communications technology due to its resistance to selective frequency fading and efficient use of spectrum. However, the security of OFDM signals remains a source of serious concern, especially in the face of network encryption that aims to disrupt communications or extract ...

A novel carrier index M‐ary differential chaos shift keying modulation scheme

IET Communications, Volume 18, Issue 19, Page 1642-1649, December 2024.
This paper proposes a novel carrier index M‐ary differential chaos shift keying modulation. By allocating part of the subcarriers to the chaotic reference for carrier index modulation and applying M‐ary DCSK modulation to data‐bearing signals, more data bits can be delivered, resulting in increased bit rate and spectral efficiency. Besides, rather than
