MODULATION APPARATUS USING MIXED-RADIX FAST FOURIER TRANSFORM |
摘要 |
An FFT (Fast Fourier Transform) processor is disclosed which is a core block of an OFDM (Orthogonal Frequency Division Multiplexing) or DMT (Discrete Multi-tone) MODEM. The FFT processor simultaneously performs sequential input and output by applying an in-place algorithm for a mixed-radix multi-bank memory, thereby realizing continuous processing with only a 2N-word memory having 4 banks. The FFT processor minimizes its complexity while satisfying a high-speed calculation requirement. |
