Abstract
An FFT apparatus for quickly processing input signals and method thereof is disclosed. In performing the FFT for processing N input signals, four N/4-point FFT units implemented by radix-2 single-path delay feedback (R2SDF) units performs the FFT with respect to the input signals, and a radix-4 computation unit performs a radix-4 computation with respect to the signals transferred from the N/4-point FFT units. Accordingly, the input signals are processed in parallel through the N/4-point FFT units, and thus a quick process of the input signals can be performed.
