Single Pixel Imaging Based on Bicubic Interpolation Walsh Transform Matrix

IEEE Access
Single pixel imaging is a new method, but imaging quality and speed are the main factors affecting its practicality. Building upon the attributes of the random measurement and deterministic matrices, a Walsh transformation matrix with bicubic ...

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’

Semi-automated bed boundary detection and log alignment using fast Walsh–Hadamard transform

Frontiers in Earth Science
Depth mismatches between well logs acquired in different runs (e.g., electrical wireline logging (EWL) versus logging while drilling (LWD)) impede stratigraphic correlation and bias reservoir property estimation.

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 ...

Characterizing and Enumerating Walsh-Hadamard Transform Algorithms

, 2017
We propose a way of characterizing the algorithms computing a Walsh-Hadamard transform that consist of a sequence of arrays of butterflies ($I_{2^{n-1}}\otimes \text{DFT}_2$) interleaved by linear permutations. Linear permutations are those that map linearly the binary representation of its element indices.
