As shown in the last subsection, kernel density estimates can be expressed as a submatrix of a certain convolution. The fast Fourier transform (FFT) is a computationally effective method for computing ...

The Fast Fourier Transform (FFT) is a fundamental building block used in DSP systems, with applications ranging from OFDM based Digital MODEMs, to Ultrasound, RADAR and CT Image reconstruction ...

He’s using a Fast Fourier Transform routine crafted in C to run as efficiently as possible on the 8-bit chip. The video after the break shows that the results are quite pleasing, with just a bit ...

Fast Fourier transforms (FFT) can be used to test the performance of a Beowulf cluster, because they involve substantial communication between nodes. These tests also allow for a comparison of various ...

The transform computation is based on a new matrix formulation of the discreet Fourier transform1 (DFT) which decomposes it into structured sets of b-point DFTs. This avoids the inherent ...

Linear transforms — like a Fourier transform — are a key math tool in engineering and science. A team from UCLA recently published a paper describing how they used deep learning techniques to ...
