Research Abstract: 
The discrete wavelet transform, DWT, is being considered for multicarrier modulation, and intensive investigations are underway on how this scheme can best be deployed. The performance of the DWT and wavelet packet transform (WPT) has been investigated and compared. There are more narrowband sub-channels in WPT than those that exist in DWT owing to the style of multiresolution adopted by the latter. However, it is found that DWT and WPT perform differently as multicarrier modulations over AWGN and multipath channels. This work helps to inform the selection of base-wavelet families when studying or designing a multicarrier system of this kind.
