FIELD: communications. ^ SUBSTANCE: present invention relates to telecommunications and can be used for transmitting information electric signals from a receiving radio centre (RRC), located in the immediate vicinity of a command signal centre, to a transmitting radio centre (TRC), located outside its limits at a distance of 5 km. N information primary electric signals with frequency Fpes i (i=1, 2,Ç,N) are transmitted from N transmitting terminal devices to the receiving radio centre. In the transmitting radio centre each of the N radio signals, meant for transmission into the radio-wave propagation medium, is power amplified and directed to the transmitting antenna. In the receiving radio centre, N information primary electric signals are converted to N radio signals with frequency frs i (i=1, 2,Ç,N), the set of which is converted to a group high-frequency signal with frequency fghf. In the transmitting radio centre, N radio signals are selected from the received group high-frequency signal, meant for transmission into the radio-wave propagation medium, with frequency frs i (i=1, 2,Ç, N). ^ EFFECT: cutting the number of conversions of the received signal and increased mobility and durability of the transmitting radio centre. ^ 2 cl, 1 dwg, 1 tbl |
