On the analysis of peak-to-average power ratio of Wavelet Packet Modulation

Wavelet Packet Modulation (WPM) is a novel multicarrier modulation technique and a promising alternative to the well established OFDM. A major drawback of multicarrier systems is their high peak-to-average power ratio (PAPR). In this paper, we study the PAPR performances of WPM systems. The novelty of the work is in the investigation of the stochastic of the WPM signals and influence of the waveshapes properties on their PAPR performances. Several well-known wavelets such as Daubechies, Symlets, Coiflets, Discrete Meyer and biorthogonal wavelet are applied. The results of this research show how these wavelet-based systems cope with PAPR.
