I reviewed some of mazdaspring's questions, that haven't been answered, mostly related to MatLab and digital communication. I fear, they haven't been read by someone, who could give a meaningful answer. They are rather specific.
It may be the case, that experts read them, but haven't been sufficiently motivated to answer. Personally, I would try to explain more detailed what I really need to know, possibly what I'm doing with that stuff. Just as an additional motivation.
