There are a number of approaches to Spread Spectrum Processing in the literature. If you do a search on NDT.net for Split Spectrum Processing, a few papers will also pop up.
There are also papers on Complex Plane Split Spectrum (CSSP) Processing which have a number of additional advantages, such as retained amplitude linearity, and further improvements in S/N ratios (among other).

A mathematical simulation of CSSP should become available on NDT.net (shareware) shortly. This software will be an extension of the currently shared diffraction simulation software (CSSP_Diff_Sim).
The link to the diffraction simulation software is as follows:
