Constellation Shaping Nonlinear Precoding and Trellis Coding for Voiceband Telephone Channel Modems : With Emphasis on Itu t Recommendation V 34, Hardcover by Tretter, Steven A., ISBN 1402070063, ISBN-13 9781402070068, Brand New, Free shipping in the US
Tretter (U. of Maryland) presents a history of the developments in signal constellation design, nonlinear pre-equalization, and trellis coding made by ITU-T Study Group XVII during its meetings to create a recommendation for a state-of-the-art voice band telephone channel modem. Topics addressed include signal constellation shaping by shell mapping, nonlinear precoding, four-dimensional trellis codes, and fast equalizer training by using periodic sequences and FFT methods. Several approaches that were considered by not accepted are also presented. A good reference for those working in the broad fields of communication theory, information theory, and modem design; also suitable as a text for an advanced graduate level course in modulation and coding.
