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, ...

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 ...

The FFT Core Library contains more than sixty Fast Fourier Transform (FFT) cores for use in Xilinx FPGAs. Cores are available with transform lengths up to 32K points for some device types, and each ...

An image simulation algorithm developed by researchers from Taiwan and the US boosts image intensity computation speed by 5,000 times Lithography, an essential process in the semiconductor industry, ...

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 ...
