Thank you for posting the additional information, it certainly helped. I'll try to do a prose explanation with less "math" in it, and then point you in what is the right direction. That's certainly a long winded problem statement, and I believe the solution is actually simpler that your professor may be making it out to be. From reading the problem ...

Petrus. First of all, thanks for attaching my github library as an update into your question for other readers. I have just seen your question. According to my own experiences, echo hiding methods are fragile towards additional echoes, so are towards reverb. A simple spread-spectrum model using a PN Sequence, which introduces some noise, embeds data into ...

From the perspective of numerical analysis, the most robust transformations are unitary orthogonal matrices because they have a condition number of one. Indeed the condition number is the metric that defines robustness. You can find this in Stuart’s Introduction to Matrix Computations or the more advanced book by Golub and Van Loan. A related way of ...
