FIELD: radio engineering, communication.
SUBSTANCE: method of transmitting information in a communication system with noise-like signals includes dividing each fragment of an array of transmitted data into 3 subarrays during transmission. The first subarray of each fragment is converted into one of predetermined pseudo-random sequences in accordance with a selected coding method; time shift is introduced into said pseudo-random sequence, said time shift being determined by the second subarray of said fragment in accordance with the selected coding method; phase keying is performed based on a law of each of the generated pseudo-random sequences with a time shift. Phase keying is performed over signals of the type sin2πfnt or sin2πfnt+π/2 depending on the value of the third subarray, where fn is carrier frequency, t is a time argument; the noise-like signal sequence is transmitted. Input data of the operation of dividing fragments of arrays of transmitted data into subarrays are the input sequences of the data to be transmitted; operations of converting the first subarray of each fragment into one of predetermined pseudo-random sequences and introducing time shift into each pseudo-random sequence are performed successively over results of the operation of dividing a fragment of an array of transmitted data into subarrays, and the operation of transmitting the noise-like signal sequence is performed over results of the phase keying operation. A combination of n+1 bits of the received fragment is determined during reception.
EFFECT: high rate of transmitting digital information.
