Abstract :
Fast Fourier transform (FFT) is widely used in OFDM. To increase the speed of data processing, there is designing a new system that is composed of two DSP subsystems and an X86-PC subsystem. In the experiment, Parallel DSP subsystems deal with the primary data. For analyzing the experiment result, the conclusion can be made that there is an outstanding capacity in dealing with FFT and the capacity can be farther improved.
