FIELD: radio engineering, possible use for increasing interference resistance of information transfer under conditions of random and intentional interference. ^ SUBSTANCE: for achieving technical result, narrowband signal is emitted simultaneously with broadband signal, interference resistance of which to intentional interference is achieved due to quasi-chaotic change of carrying frequency. Broadband route is used for concealed introduction of low speed control signals into transfer synchronism and generation of frequency-time code, adapting to interference situation with removal of negatively affected frequencies, while narrowband route, adjustable in accordance to adaptive frequency-time code, is used for transferring high speed information. Both broadband and narrowband signals are transferred simultaneously. ^ EFFECT: increased resistance to interference, increased information transfer speed. ^ 2 dwg |
