Vector fitting realisation of exact time domain modal nonreflecting boundary condition [PDF]
, 2010 To employ the modal nonreflecting boundary condition (MNRBC) in cylindrical coordinates in the finite element time domain (FETD) method, a time domain kernel expression must be found that it is the inverse Laplace transform (ILT) of a known frequency ...

Frequency Domain Image Filtering Using CUDA [PDF]
Mehran University Research Journal of Engineering and Technology, 2014 In this paper, we investigate the implementation of image filtering in frequency domain using NVIDIA?s CUDA (Compute Unified Device Architecture). In contrast to signal and image filtering in spatial domain which uses convolution operations and hence is ...

Frequency Domain Filtering Method for SSVEP-EEG Preprocessing
IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2023 Steady-state visual evoked potential (SSVEP) signal collected from the scalp typically contains other types of electric signals, and it is important to remove these noise components from the actual signal by application of a pre-processing step for ...

Reliability-Aided Multiuser Detection in Time-Frequency-Domain Spread Multicarrier DS-CDMA Systems
, 2009 In this contribution we propose and study a novel multiuser detection (MUD) scheme for multicarrier direct-sequence code-division multiple-access systems employing both time (T)-domain and frequency (F)-domain spreading, which are referred to as the TF ...

Moving Objects Detection Based on Frequency Domain
مجلة بغداد للعلوم, 2020 In this research a proposed technique is used to enhance the frame difference technique performance for extracting moving objects in video file. One of the most effective factors in performance dropping is noise existence, which may cause incorrect ...
