This document provides information about PhD filter MATLAB code and projects from www.matlabsimulation.com. It lists several types of basic filters supported, including low pass, high pass, band pass, coloring filters, and Wiener and adaptive filters. It also discusses MATLAB code topics and guidance for projects related to transmission systems, fingerprint-based indoor positioning, lens-free imaging, and breast imaging radar approaches. Finally, it lists several recent PhD filter MATLAB code projects involving image sensing, plenoptic image manipulation, sketch databases, and structural brain imaging analysis.
