Utilizing the advantage of concentrating energy to certain subspaces of the discrete wavelet transform (DWT), a novel peak-to-average power ratio (PAPR) reduction method for wavelet-based multicarrier modulation (WMCM) systems is proposed and presented in this paper. Both theoretical analyses and simulations are carried out to prove the feasibility of the proposed method. PAPRs are investigated by employing different thresholds. The distortions of the wavelet transform caused by the threshold are measured in terms of the mean square error (MSE). This paper also investigates the bit error rate (BER) performance of threshold controlled WMCM systems. All results given in this paper are based on a limited class of wavelets. However, this method can be adapted to WMCM system with other kinds of wavelets as well, since almost all kinds of wavelets have this similar characteristic used in the threshold control method. Therefore, we conclude that the proposed threshold method is an efficient technique for WMCM systems.
