FIELD: radio engineering and communication.
SUBSTANCE: invention relates to broadband radio measurement systems. To this end, disclosed is a method for synthesis of broadband signals based on the use of composite code structures, consisting in the fact that on the transmitting side in radio systems, cycles or frames of transmitted digital information are formed, each of which contains m binary symbols, a spreading pseudorandom sequence is formed. In a single composite code structure, a number of code sequences K is formed, which is a multiple of four, generating inverse and shift-invariant code sequences for generating a full alphabet of code sequences used for transmitting wideband signals by selecting sequences, total autocorrelation function of which has no side lobes, and the main maximum is equal to K × N, wherein the shift-invariant binary code sequence is a sequence whose bits are mirror-filled with 0 and 1 relative to the initial binary code sequence.
EFFECT: high structural security and noise immunity of broadband signals.
