A novel architecture is proposed to implement FFT/IFFT processor with CPLD devices.The new architecture combines the traditional pipeline structure with recycled structure effectively and meets the requirement of 802.11a

[1]

standard.Especially

it utilizes far fewer logic cells than other architectures.In order to verify the efficiency of the proposed structure

we implement the proposed structure and the traditional pipeline structure with CPLD devices separately

and the experimental results show that the proposed structure hereof has superiority in application.
