You can try using smoothing filters to remove the existing noise from your image.

Why would you _have_ to use wavelets?
I've done image denoising for some time and never have _had_ to use wavelets.

Obvious answer: because it's a homework assignment.
Well if it is a homework assignment then you should go through your professor's class notes or google papers which discuss about denoising using wavelets.
