An important look at bandwidth-efficient modulations with
applications to today’s Space program
Based on research and results obtained at the California Institute
of Technology’s Jet Propulsion Laboratory, this timely book
defines, describes, and then delineates the performance (power and
bandwidth) of digital communication systems that incorporate a wide
variety of bandwidth-efficient modulations appropriate for the
design and implementation of space communications systems.
The author compares the performance of these systems in the
presence of a number of practical (non-ideal) transmitter and
receiver characteristics such as modulator and phase imbalance,
imperfect carrier synchronization, and transmitter nonlinearity.
Although the material focuses on the deep space applications
developed at the Jet Propulsion Laboratory, the presentation is
sufficiently broad as to be applicable to a host of other
applications dealing with RF communications.
