FIELD: physics; radio.
SUBSTANCE: present invention pertains to radio engineering and can be used in radio systems, meant for setting up a radio communication channel for broadband signals with pseudorandom operational frequency readjustment. Device comprises transmitter and, at least, one receiver. The transmitter comprises source of information, pseudorandom sequence generator (PSG), K sources of modulated signal, K tuneable forced oscillations generators, K controlled broadband attenuators, a unit for controlling the broadband attenuators and a unit for holding and dividing the code of PSG into K commands. The receiver comprises broadband filter, tuneable band-pass filter, signal demodulator, pseudorandom sequence generator and delay circuit.
EFFECT: lower level of out-of-band emissions.
