Accurate frequency estimation in a wideband digital receiver using the FFT algorithm encounters challenges, such as spectral leakage resulting from the FFT’s assumption of signal periodicity.

Abstract: The fast Fourier transform (FFT) is the main method of electrical signal analysis, but there are difficulties in performing non-synchronized sampling when FFT is applied to analyze broadband ...

音声データの中に「どんな音（周波数）」が含まれているかを調べるためには、フーリエ変換（Fourier Transform）が欠かせません。 特にデータサイエンスや機械学習の分野では、音声特徴量抽出の第一歩として高速フーリエ変換（FFT: Fast Fourier Transform）が頻繁 ...

Abstract: When the fast Fourier transform (FFT) algorithm is used to analyze demodulate interference signal, nonsynchronous sampling of the interference optical spectrum would cause spectral leakage ...
