FIELD: information technologies.
SUBSTANCE: on a transmitting side a bearing oscillation is modulated with a noise-like signal, besides, each symbol of alphabet at is coded by means of the NLS with its repetition period Ti, which is different from others, and at a receiving side the values of autocorrelation function Y(τ) are found in points τ = Ti, 2Ti, ..nTi, then amounts 
are calculated, and aj value is assigned to the received signal, for which the sum S(Tj) is the maximum.
EFFECT: higher noise immunity due to more complete usage of information enclosed into the autocorrelation function of a periodic noise-like signal.
