Abstract

On the wavelet-packet modulation scheme, wavelet packets are used as carriers, where information to be transmitted is encoded, via an inverse wavelet packet transform, as the coefficient of wavelet packets. The power spectrum density (PSD) of the modulated signals describes the property of modulation in frequency domain, which is discussed by many researchers by simulation. In this paper, the formula of the PSD of the modulated signals is derived. The characteristics of the modulated signals, such as spread spectrum and spectral flatness, is shown from the formula.
