Document Type and Number:
Japanese Patent JP2012090069
Kind Code:
A
Abstract:
To provide a fast Fourier transform (FFT) device having small power consumption.
An FFT device performs FFT processing on a symbol signal column of time series, and includes: a first memory 5 that stores a first symbol, stores intermediate data of the FFT processing performed on the first symbol, and stores processing result data of the FFT processing performed on the first symbol; and a second memory 6 that stores a second symbol input to the FFT device after the first symbol, stores intermediate data of the FFT processing performed on the second symbol, and stores processing result data of the FFT processing performed on the second symbol.
