Reducing multi-carrier signal peak to average power ration has an important significance in the design and study of modern power amplifier. In this paper, based on the envelope characteristics of multi-carrier signal, a novel technique for reducing peak to average power ratio is proposed. The results of theoretical analysis and computer simulation show that the proposed technique can moderately change signal's envelope distribution, so that greatly reducing the peak to average power ratio of multi carrier. The results also show that the linearity of the amplifier using this new technique is significantly better than that of existing amplifier..
