RA scholtz does work with signal processing and spread spectrum communication. i'm embarrassed to say that i really don't know much more about it. i think i fall into that trap where everything sounds really fascinating, regardless of whether i understand it or not, so sometimes i'll just smile and nod. i'm both easily entertained, and easily impressed. at least, by math stuff. thankfully, i don't think most of these people notice if i have a blank look on my face.
