Reihe: JPL Deep-Space Communications and Navigation Series

An important look at bandwidth-efficient modulations withapplications to today's Space program
Based on research and results obtained at the California Instituteof Technology's Jet Propulsion Laboratory, this timely bookdefines, describes, and then delineates the performance (power andbandwidth) of digital communication systems that incorporate a widevariety of bandwidth-efficient modulations appropriate for thedesign and implementation of space communications systems.
The author compares the performance of these systems in thepresence of a number of practical (non-ideal) transmitter andreceiver characteristics such as modulator and phase imbalance,imperfect carrier synchronization, and transmitter nonlinearity.Although the material focuses on the deep space applicationsdeveloped at the Jet Propulsion Laboratory, the presentation issufficiently broad as to be applicable to a host of otherapplications dealing with RF communications.
An important contribution to the scientific literature,Bandwidth-Efficient Digital Modulation with Application to DeepSpace Communications
* was commissioned by the JPL Deep Space Communications andNavigation System Center of Excellence
