Wavelet Extraction using an SSP-to-SSP Transform

By Chaiwoot Boonyasiriwat and Shuqian Dong

Figure 1. True wavelet and extracted wavelet.

Objective: Learn how to extract a wavelet using an SSP-to-SSP transform.

Introduction: Wavelet Extraction

Procedure:

1. Download the Matlab codes and data from wavelet.zip.
2. Extract the file into your directory using the Windows built-in unzip utility (Right-click at the file and choose Extract All File).
3. Run program wavelet.m in Matlab to obtain the extracted wavelet.

Questions:

1. What are the advantages and disadvantages of this method?
2. Would it work when the source signature is not the same for all the sources?

Exercise:

1. Extract a wavelet from the following dataset (data.zip).
