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’

An efficient quantum algorithm for ensemble classification using bagging
IET Quantum Communication, Volume 5, Issue 3, Page 253-268, September 2024.A new quantum algorithm that exploits quantum superposition, entanglement, and interference to build an ensemble of classification models is introduced. Thanks to the generation of several quantum trajectories in superposition, the authors obtain an exponentially large number of base models increasing only linearly the depth of the correspondent ...

Advances in Quantum Imaging with Machine Intelligence
Laser &Photonics Reviews, Volume 18, Issue 8, August 2024.Quantum imaging exemplifies the fascinating and counter‐intuitive nature of the quantum world, where non‐local correlations are exploited for the imaging of objects by remote and non‐interacting photons. The field has exploded of late, driven by advances in the fundamental understanding of these processes, but also by advances in technology.

Anomaly Detection for Suspension Systems Based on the Gaussian Distribution of Hyperspheres
机车电传动, 2021 The abnormality of the suspension system means that the operating state of the suspension system does not match the expected state, and the system has no faults in the actual operation of the middle-low speed maglev train.

A composite spread spectrum sequence for underwater acoustic signal acquisition
IET Communications, Volume 18, Issue 11, Page 689-700, July 2024.This article explores the acquisition performance of spectrum spread sequence based on underwater acoustic (UWA) channel. To overcome the limitations of conventional sequences, a composite chaotic orthogonal sequence (CCOS) is proposed as spectrum spread sequence and a source‐target model is constructed for simulation. In addition, a parallel algorithm
