We first discuss two approaches for designing complex wavelet packets which can be used as orthogonal carriers for modulations like QAM and PM, and then compare the performance of the wavelet packet based modulation scheme with that of discrete multitone modulation using DFT bases. The results show that the wavelet packet based scheme yields a lower average bit error probability compared to the DFT based scheme. The improved performance of the wavelet packet based scheme is because of the spectrally contained nature of the wavelet packet bases which are under the control of the designer
