Simulating, Predicting, and Minimizing False Peaks for Hadamard Transform Ion Mobility Spectrometry.
Journal of the American Society for Mass Spectrometry, 2020Multiplexing techniques, including the Hadamard Transform, are widely used in the recovery of weak signals from high-level noise. Hadamard transform ion mobility spectrometry (HT-IMS), however, can suffer serious drawbacks due to false peaks. False peaks

A New Fast Algorithm for Discrete Fractional Hadamard Transform
IEEE Transactions on Circuits and Systems Part 1: Regular Papers, 2019This paper proposes a new fast algorithm for calculating the discrete fractional Hadamard transform for data vectors whose size $N$ is a power of two. A direct method for the calculation of the discrete fractional Hadamard transform requires $O(N^{2})$

Quaternion Hadamard Transform and QR Decomposition Based Robust Color Image Watermarking
2019 3rd International Conference on Trends in Electronics and Informatics (ICOEI), 2019A robust watermarking method depending on Quaternion Hadamard Transform (QHT) and QR decomposition is proposed. The QHT can preserve the relationship among the rgb component and color information.

Fault Detection on Series Capacitor Compensated Transmission Line using Walsh Hadamard Transform
2018 International Conference on Computing, Power and Communication Technologies (GUCON), 2018In this paper, a fault detection scheme for series capacitor compensated three phase transmission lines is proposed using fast Walsh hadamard transform. The proposed scheme uses only single end measured fault current data.
