This paper presents a reconfigurable FFT architecture for variable length and multistreaming WiMax wireless standard. The architecture processes 1 stream of 2048-pt FFT, up to 2 streams of 1024-pt FFT or up to 4 streams of 512-pt FFT. The architecture consists of 11 SDF pipelined stages and radix-2 butterfly is calculated in each stage. The sampling(More)
