A new algorithm performs Fourier transforms using a minimal number of samples. The fast Fourier transform, one of the most important algorithms of the 20th century, revolutionized signal processing.

Modern video coding architectures are at the forefront of addressing the increasing demands for efficient data compression, high-resolution broadcasting, and real-time processing in a global ...

Sparse Fourier Transform (SFT) algorithms constitute a transformative approach to spectral analysis by leveraging the inherent sparsity of signals in the frequency domain. In contrast to the ...

The Burrows-Wheeler transform is a string transformation algorithm invented by British computer scientists Mike Burrows and David Wheeler, and is used in compression algorithms, etc. Google has ...

Researchers have developed a new algorithm that, in a large range of practically important cases, improves on the fast Fourier transform. Under some circumstances, the improvement can be dramatic -- a ...
