Abstract
Provided are a method and apparatus for performing a variable point Inverse Fast Fourier Transform (IFFT)/Fast Fourier Transform (FFT). The apparatus for performing a variable point IFFT includes: an IFFT interpolator generating interpolation data signals having a determined point and interpolating a plurality of interpolation data, the number of which depends on an IFFT operation mode signal into input data; an IFFT operator generating IFFT operation data signals by performing an IFFT operation for the interpolated data signals; an IFFT mode selector selecting and outputting some of the IFFT operation data signals in response to the IFFT operation mode signal so that the selected IFFT operation data have the same number of points as the input data; and a control unit outputting the IFFT operation. Therefore, it is possible to easily compute variably sized IFFT/FFT hardware.
