An efficient multiplier design method for predetermined coefficient groups is presented based on the variation of canonic signed digit (CSD) encoding and partial product sharing. By applications to radix-24 FFT structure and the pulse-shaping filter design used in CDMA, it is shown that the proposed method significantly reduces the area, propagation delay and power consumption compared with previous methods.
