Interference-Protected Radio Communication System Using a Repeater

Methods of ensuring interference immunity in radio relay systems, radio communication systems between ground stations and unmanned ground vehicles or unmanned aerial vehicles are considered. On the basis of the conducted analysis, it is proposed to use special signals in the system characterized by increased interference immunity, as well as to include a repeater in the system. Mathematical modeling of the radio channel between two ground stations or vehicle and a ground station has been carried out for various types of vehicles and ground stations in the absence or presence of a repeater in the system. The technical characteristics of the variants of the proposed system are calculated. Based on the results of the research, a structural diagram of an interference-protected radio communication system using a repeater is proposed.
