摘要：

In this paper we propose a method to reduce the Peak-to-Average Power Ratio (PAPR) in the developmental Wavelet Packet Multi-carrier Modulation (WPM) system. The method works on the principle that the PAPR of a multicarrier system can be adjusted by varying the phase-shifts of the subcarriers. Hence different PAPR values for the same information can be obtained by randomly altering the phases of the sub-carriers used to modulate the data. The WPM frame with the least PAPR is then identified and transmitted. The attraction of the method is in its simplicity and elegance of implementation and the notable gains it yields with minimal increase in complexity.
