From the de-nosing results of all filters it can be concluded that overall performance of DWT and CDTDWT is admirable in LENA PET SPECT and X- Rays.
Therefore, the BW efficiency of the DWT system is 3 times better the DCT system with their DAPSK modulation.
This means the DWT system possesses two times better BW efficiency than the DCT system.
Figures 6a through 6c compare the BW efficiency performance of the DWT & DCT systems with and without companding to that of with exponential transform.
However, the performance of the DCT with QAM modulation is not as good as the DWT system.
