Hi, I'm an undergraduate in computer engineering, with emphasys in embedded systems and digital signal processing. I have experience in academic area using MATLAB, so I think I would be a good fit for your project.
Actually, my last project in freelance was an academic one, which I've used MATLAB to modulate and demodulate a voice signal, I can show you samples of it.
Since I'm just an undergraduate, I might not be as experience as you want, but I think we could exchange knowledge and would be good for either of us.
