Analysis compares amplitude and phase modulation methods for effective quantum key distribution in satellite communication, highlighting noise immunity implications.
We examined several widely used amplitude and phase modulation methods for classical signals for exchanging support information in the process of quantum key distribution in satellite-to-ground communication. Based on the communication channel modeling, we compare noise immunity and the useful information transmission rate for various types of modulation as the main characteristics of communication protocols.
