—Wavelet packet modulation (WPM) is used as an alternative to orthogonal frequency division multiplexing (OFDM) as multicarrier modulation (MCM) technique, recently. High peak-to-average power ratio (PAPR) value of the MCM signals decreases the systems performance due to using nonlinear amplifier in the system transmitter. Generally, partial transmit sequence (PTS) technique is used to reduce PAPR in MCM systems. In this paper, we use the artificial bee colony (ABC) algorithm to reduce the PAPR value of the PTS for WPM signals. The performance of the artificial bee colony algorithm for 6th Daubechies wavelets was compared with the original WPM for different Daubechies wavelets, random search PTS for 6th Daubechies wavelets and optimum PTS by computer simulations.
