Summary:
This paper presents a design and implementation result of a high-speed, low-complexity four data-path 64-point radix-24 FFT/IFFT processor for high-throughput MIMO-OFDM wireless LAN system. The proposed FFT/IFFT processor can provide a higher throughput rate and low hardware complexity by using a four-parallel data-path scheme and a multipath delay feed-back (MDF) structure. The proposed four data-path 64-point MDF FFT/IFFT processor has a throughput rate of up to 600 M sample/s at 150 MHz while requiring much smaller hardware complexity satisfying IEEE 802.11n standard requirements.
