IEEE Communications called the first edition "extremely useful ... likely to become a standard reference" - and engineers worldwide have agreed! This newly revised and expanded edition of an Artech House classic builds on its success as far and away the most comprehensive guide to digital modulation techniques used in communications today. It devotes five new chapters to orthogonal frequency division multiplexing (OFDM), the hottest new bandwidth-efficient technique, and includes new modulations for optical communications. It also adds a fast-access comparison of all modulation schemes that will prove popular with engineers for any number of research and design tasks.

Engineers get full details for every technique including operation principles, bit error probability, spectral characteristic, modulator, demodulator, synchronizer, performance in fading channels, comparison with other techniques, and applications. The book is packed with nearly 400 illustrations and includes new appendixes covering trigonometry identities, Fourier transform pairs and properties, and Q-function and error function values that provide even more time-saving reference help for today's busy engineer.
