The implemented template class recursion has P levels. Every FFT calculation process runs from level P to level 1, while the level 1 is empty (Listing Three, in part one of this article). Some ...
Dự án nghiên cứu và so sánh hiệu năng giữa FFT tuần tự và FFT song song hóa sử dụng OpenMP, đồng thời ứng dụng FFT vào xử lý ảnh trong miền tần số.
The Fast Fourier Transform is one of the most important algorithms in scientific computing, used in signal processing, image compression, wireless communications, and machine learning. This ...
This article presents two important DSP techniques, the overlap-add method, and FFT convolution. The overlap-add method is used to break long signals into smaller segments for easier processing. FFT ...
Abstract: To address the issues of low Doppler frequency offset estimation accuracy and low acquisition probability in traditional PMF-FFT acquisition algorithms under low signal-to-noise ratio (SNR) ...
Abstract: In the FFT harmonic analysis algorithm, the analysis error is often caused by the spectrum leakage effect caused by asynchronous sampling. Therefore, it is ...
