In this paper, based on the variation of the modified Booth encoding method, an efficient modified Booth multiplier design method for predetermined coefficient groups is proposed. In the case of pulse-shaping filter design used in CDMA, it is shown that by the proposed method, area and power consumption can be reduced up to 44% and 48%, respectively, compared with the conventional designs. Also, it is shown that in the case of 128-point radix-24 FFT, the area and power consumption can be reduced by 18% and 36%, respectively.
