Here is a sophisticated discussion of long-term development in advanced physical layer techniques designed for broadband communications, for fixed and mobile terminals, and 4G evolutions and possible convergence between different technologies. The authors provide state-of-the-art coverage on all aspects of the physical layer of a satellite link, including channel propagation, coding, modulation, synchronization and parameter estimation, predistortion and equalization, diversity and combining, multiple access, and software radio. Additionally, a general description of satellite systems and services is provided for organizing the material into a generalized and workable framework.
