FIELD: digital communication.
SUBSTANCE: invention can be used to eliminate error in symbol synchronization and error of carrier frequency from communication signal with several carriers and digital modulation. System to remove error of symbol synchronization and error of carrier frequency from signal with orthogonal frequency-division multiplex incorporates aid for reception of modulated signal of orthogonal frequency-division multiplex which presents sequence of symbols of orthogonal frequency-division multiplex, peak former that forms boundary signal comprising assemblage of signal peaks, signal amplifier, aid establishing time position, aid for removal of error by carrier frequency of received signal of orthogonal frequency-division multiplex.
EFFECT: development system with optimal reconstruction of symbol synchronization and carrier frequency from signal with several carriers and digital modulation.
