Engineers have solved a 50-year-old puzzle in signal processing. They've formulated the 'inverse chirp z-transform,' an algorithm related to one that's running on your cell phone right now. It took ...

In this paper, a Fast Fourier Transform (FFT) or inverse FFT processor for Fifth-Generation (5G) Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) system’s ...

The Fast Fourier Transform (FFT) and Inverse Fast Fourier Transform (IFFT) play vital role in signal processing. It is often used in many communication systems. The proposed paper produces realization ...

Flowchart of the proposed algorithm for speeding up the aerial image simulations in computational lithography. By scaling up the input data appropriately, one can apply the fast Fourier transform (FFT ...

AMES, Iowa – Something called the fast Fourier transform is running on your cell phone right now. The FFT, as it is known, is a signal-processing algorithm that you use more than you realize. It is, ...
