Modulation Techniques for Satellite Communications

White Paper

Almost every communication industry — including broadcasting, navigation, transportation, and cellular — relies on satellite technology in some way. Applications and services for satellite communications include broadband communications, mobile satellite services, and weather forecasting. Emerging applications and services for satellite communications include in-flight connectivity, connected car, and 5G New Radio non-terrestrial network.

 

With strong demand for faster data throughput, satellite communications use complex modulation schemes to improve their spectral efficiency. The modulation techniques for satellite communications require not only faster data rates but also minimizing the impact of nonlinear amplification in the radio-frequency (RF) power amplifier.

 

This white paper focuses on modulation techniques for modern satellite communications from generating and analyzing the signals to the impacts of phase noise on modulation quality.
