In this paper, we propose a new efficient FFT algorithm for OFDlwDMT applications and present its pipeline implementation results. Since the proposed algorithm is based on the radix-4 butterfly unit, the processing rate can be twice as fast as that based on the ~ a d i x 2 ~ algorithm. Also, its implementation is more area-eficient than the implementation from conventional radix-4 algorithm due to reduced number of nontrivial multipliers like using the radix23 algorithm. In order to compare the… CONTINUE READING
