I'm a digital ASIC engineer looking for some *beginner* (not reference/advanced!) books on Orthogonal Frequency Division Multiplexing (OFDM.) Well, hopefully such a book exists?
The book I already have "Multi-carrier Digital Communications: Theory and Applications of OFDM" (by Bahai, Saltzberg, and Ergen) seems a bit beyond me. It's a great reference for researchers, but as you've probably guessed, it's difficult for math-challenged engineers like myself to put that into practice.
