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(More)
Early detection of breast cancer using a radio frequency application is technically challenging, but potentially of great importance since it would be fast and cheap to implement. This paper explores an ideal ultra-wideband application for detecting tumour cancer within breast tissues using an FDTD numerical method. 1D, 2D and 3D FDTD models are(More)
