FIELD: radio engineering and telecommunications.
SUBSTANCE: invention can be used for synthesis of multi-frequency signals when transmitting information over wireless communication lines under the influence of band interference via the radio system for transmitting information. The technical result is achieved by placing reserved tones on carriers of the OFDM signal affected by band interference.
EFFECT: increase in throughput of the data transmission channel together with a decrease in the magnitude of the peak factor in radio information transmission systems using multi-frequency signals, in this case OFDM signals, in presence of band interference in the data transmission channel.
