Optimizing PAPR by Linear Programming in wavelet packet modulation

Abstract

High peak-to-average power ratio (PAPR) of the transmit signal is a major drawback of wavelet packet modulation (WPM). The article presents a new method to reduce PAPR by Linear Programming (LP) to select the optimal wavelet packet basis. Numerical and simulation results show the signal modulated by the selected wavelet packet basis has the optimal PAPR… (More)
