See the help for wden() to implement denoising using the orthogonal discrete wavelet transform.
See the help for spectrum.periodogram to see how to compute a PSD estimate.

By the way, beginning with R2011b, you can use the interactive tool, wavemenu, and generate MATLAB code for wavelet denoising.
