satellite communication, OFDM, cyclic prefix, OFDM symbol, multipath time


To study the method of selecting the optimal duration of the prefix OFDM-symbols in satellite communication channels, the original model of the communication line "Aircraft satellite-ground station" was built. The adaptive modulation model consists of an information source, an aircraft transmitter, an uplink / downlink, a satellite transponder, and a ground station receiver. OFDM technology for combating the effects of multipath is considered. The method of combating intersymbol interference based on the use of OFDM technology has been improved.
