Do you need to know what signal type to select for a wireless application? Quickly develop a useful expertise in digital modulation with this practical guide, based on the author's experience of over thirty years in industrial design. You will understand the physical meaning behind the mathematics of wireless signals and learn the intricacies and tradeoffs in signal selection and design. Six modulation families and twelve modulation types are covered in depth, together with a quantitative ranking of relative cost incurred to implement any of twelve modulation types. Extensive discussions of the Shannon Limit, Nyquist filtering, efficiency measures and signal-to-noise measures are provided, radio wave propagation and antennas, multiple access techniques, and signal coding principles are all covered, and spread spectrum and wireless system operation requirements are presented.Read more

Reviews & endorsements
"More experienced readers, especially those who return to the book later on, will find details in the unique explanations that offer greater insight into principles they thought they already knew."
- Gary Breed, High-Frequency ElectronicsSee more reviews
"a perfect balance of theory, practice, and depth...a fun tour of signals, noise, circuit techniques, wireless propagation limitations, the math of error correction codes, and the limits of information transfer." - Alfy Riddle, IEEE Microwave Magazine December 2011
