Abstract
Satellite communication and cellular communication systems have not been cooperative for use cases during the past two decades. However, recent research seriously takes into account consolidating satellite and cellular communication systems in 5th and 6th generation (5G and 6G) wireless communications. This paper analyzes the potential symbol error rate (SER) performance considering 5G coordinated multi-point (CoMP) transmission with the satellite and next-generation Node B (gNB), considering adaptive modulation in satellite communication downlink. The comprehensive simulations consider higher-order modulation schemes than those conventionally supported by the satellite in a variety of scenarios in terms of phase noise, modulation order, and altitude of satellite or unmanned aerial vehicle (UAV). The simulation results exhibit that satellites or UAVs need to adaptively change their modulation schemes.
