Lihong Jia, Yonghong Gao, Jouni Isoaho, Hannu Tenhunen · 2002
In this paper, we present a new VLSI-oriented fast Fourier transform (FFT) algorithm-radix-2/4/8, which can effectively minimize the number of complex multiplications. This algorithm can be implemented efficiently using a pipelined architecture. Based on this pipelined architecture, an 8 K FFT ASIC is designed for use in the DVB (Digital Video Broadcasting) application in 0.6 /spl mu/m-3.3 V triple-metal CMOS process.
