recommendations! Published in 2018 at "Optik"

DOI: 10.1016/j.ijleo.2017.09.004

Abstract: Abstract The algorithm of SFT (sparse Fourier transform) is firstly used for monochromatic light spectrum reconstruction in this paper. Due to the increasing amount of interference data, the operation efficiency of traditional algorithms is not… read more here.

DOI: 10.1109/access.2022.3169603

Abstract: The wireless distributed transient shockwave testing system based on Nyquist sampling needs to keep high sampling rate and front-end data processing rate, which leads to the shortening of the life cycle of wireless nodes. In… read more here.

recommendations! Published in 2017 at "IEEE Transactions on Aerospace and Electronic Systems"

DOI: 10.1109/taes.2017.2714918

Abstract: The Sparse Fourier Transform (SFT), designed for signals that contain a small number of frequencies, enjoys low complexity, and thus is ideally suited for big data applications. In this paper, we propose Robust Sparse Fourier… read more here.

DOI: 10.1109/tsp.2022.3205758

Abstract: The fast approximation algorithm of non-uniform discrete Fourier transform (NUDFT) is an important issue in signal processing. In this paper, a novel estimation algorithm is constructed for NUDFT-II, which is the general form of the… read more here.
