FIELD: information technology. ^ SUBSTANCE: method involves simultaneous emission of several amplitude- and phase-shift keyed useful signals and a masking signal, summation thereof and suppression of the masking signal during reception, wherein the masking signal emission used is not only similar to the useful signal on polarisation, spatial, time and frequency parameters, but also overlaps the frequency variation range of each useful signal emission; two reference signals with equal initial phases are generated, wherein all parameters of one of them coincide with parameters of the emitted useful signal, and the second reference signal is distinguished only by carrier frequency; a mutual correlation function is generated between the receiving additive family of the masking signal and the corresponding reference signal, and the second mutual correlation function is subtracted from the first. ^ EFFECT: higher security of transmitting information. ^ 3 cl, 12 dwg |
