A New Fast Walsh Hadamard Transform Spread UW-Optical-OFDM Waveform
2022 30th Signal Processing and Communications Applications Conference (SIU), 2022In this study, it is recommended to apply the UW-OFDM waveform, which is offered as an alternative to classical OFDM in 5G and beyond waveform design research and development studies used in radio frequency (RF) communication, in optical OFDM systems.

Fast Walsh-Hadamard Transform and Smooth-Thresholding Based Binary Layers in Deep Neural Networks [PDF]
2021 IEEE/CVF Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2021 The paper (v1) has been accepted to CVPR 2021 BiVision Workshop. We notice the final Conv2D is also a 1x1 convolution layer so we update the result with changing the layer in v2. In v3, we update citation 37 because its authorship changes. In v4, we propose the improved version of smooth thresholding called "weighted smooth thresholding"

A parameterisable fast Walsh-Hadamard transform
2023The aim of this thesis was to create a parameterisable Fast Walsh-Hadamard Transform in the form of a robust intellectual property core. This paper provides background information on the Walsh-Hadamard Transform (WHT), reprogrammable hardware and the current state of the intellectual property (IP) industry.

Optimized fast Walsh-Hadamard transform on OpenCL-GPU and OpenCL-CPU
2016 Sixth International Conference on Image Processing Theory, Tools and Applications (IPTA), 2016The Walsh-Hadamard transform plays a major role in many image and video coding algorithms. In one hand, its intensive use in these algorithms makes its acceleration a challenge, in order to speed-up the algorithm execution. On the other hand, the available fast implementations are not efficient across different platforms. In this work, a parallel-based

A fast algorithm of finding the diagonal elements of the covariance matrix of the two-dimensional Walsh-Hadamard (WH) transform of data is described. Its usefulness and other interesting properties of the WH transform are discussed. The performance of the WH transform is compared with the Karhunen-Loeve transform for a first-order stationary Markov ...

Quantum computers are based on quantum physics, and can exploit quantum effects to boost its computation. However, analysis of quantum algorithms are often hard since quantum algorithms are, in some sense, parallel algorithms (called quantum parallelism) and its behavior is unintuitive.

A Novel ACO-OFDM System Based on Fast Walsh Hadamard Transform
2020 International Conference on Electrical, Communication, and Computer Engineering (ICECCE), 2020Visible Light Communication (VLC), an alternative to radio frequency (RF), was born as a promising technology. In VLC systems, orthogonal frequency division multiplexing (OFDM) has received much attention due to its high data rate, simple equalization and robustness against inter symbol interference (ISI).

One of the main goals of a brain computer interface (BCI) is to enable a communication channel between the brain and electronic devices by converting neural activity into control commands either for devices or applications. Because of the excellent temporal resolution, low set-up cost, and non-invasive nature, BCI systems generally use ...

User authentication scheme based on Fast-Walsh Hadamard transform
2015 International Conference on Circuits, Power and Computing Technologies [ICCPCT-2015], 2015User authentication scheme in context of audio can be achieved by labeling the speech signal with key signal dependent physical features. The key features for the development of the label are identified by using the common classification schemes such as ANN, kNN and SVM.
