Title: Fast fourier transform apparatus having parallel grid frame structure
Inventor: WU AN-YU
IPC: G06F17/14
Filed: 1998-05-28
Granted: 2001-01-11
Abstract: This invention is about a Fast Fourier Transform (FFT) apparatus that is suitable for use in the discrete multi-tone modulation system and can be realized by very large scale integrated circuit. According to this invention, the inverse FFT function/forward FFT function is modified to avoid the operation of complex number. In addition, this invention utilizes time recursive parallel grid structure to reduce the hardware complexity required for the inverse FFT/forward FFT; for an example of 512 (N=256) points, the number of multiplier required is 11% of that required for the conventionally known one (Cooly-Tukey) and the number of required adder is 9% of that needed for the conventionally known one. For large discrete multi-tone modulation system or OFDM (Orthogonal Frequency Division Multiplexing) receiving/transmitting system, this invention is the best solving means for reducing the production cost.
