Good book. Dr. Stuber was my teacher at Georgia Tech. At that time we were using Proakis book (Digital Comm.), yet, I always went back to this concise book for precise information on those confuse subjects like adaptive filtering. It's full of formulas and theory; it covers adaptive filtering including MLSE, Viterbi, and algorithm like the Steepest Descent or the practical MLS. It is not a Filtering book, yet it does covers the essentials. It covers Modulation and Demodulation, Detection, Estimation, Fading channels etc etc. It is a good reference book writing by a pioneer in the field. I do recommend this great book for a complete engineer's library. In fact I have just purchase the new edition. Thank you Dr. Stuber.
