What are the benefits and drawbacks of using different modulation and coding schemes for SATCOM?
Satellite communications (SATCOM) rely on modulation and coding schemes to transmit and receive signals over long distances and noisy channels. Modulation is the process of changing the characteristics of a carrier wave, such as amplitude, frequency, or phase, to encode information. Coding is the process of adding redundancy or error correction to the information bits, to improve the reliability and efficiency of the transmission. Different modulation and coding schemes have different benefits and drawbacks for SATCOM, depending on factors such as bandwidth, power, data rate, and channel conditions. In this article, we will explore some of the common modulation and coding schemes used for SATCOM, and how they affect the performance and design of satellite systems.
