Choice of physical layer parameters for mobile satellite broadcast
Abstract
This chapter assesses the choice of the physical layer parameters (code rate, modulation, time interleaving) that are best suited for satellite broadcast. The optimum choice depends on the system s envisaged spectral efficiency or available signal-to-noise ratio, and the target usage environment, like rural or sub-urban reception. The analysis is carried out by means of information theory and evaluation of satellite field measurements.
