Abstract: An accurate frequency estimator of complex sinusoid in additive white noise is proposed. It is based on interpolation of Fast Fourier Transform (FFT) and Discrete-Time Fourier Transform ...
Abstract: Multistatic millimeter-wave (MMW) imaging systems offer advantages in imaging objects with high contour complexity. Traditional reconstruction algorithms, such as the Back Projection (BP) ...
PFFFT does 1D Fast Fourier Transforms, of single precision real and complex vectors. It tries do it fast, it tries to be correct, and it tries to be small. Computations do take advantage of ...
The Discrete Fourier Transform (DFT) converts N time-domain samples into N frequency-domain coefficients, revealing the spectral content of a signal. The naive DFT requires O(N²) complex ...
