FIELD: radio engineering, communication.
SUBSTANCE: method for transmitting information by multi-frequency signals is characterized by successive steps: converting the sequence of information symbols into a combination of modulating symbols, generating a multi-frequency signal as a sum of orthogonal partial signals of different frequencies, each modulated in phase by an appropriate modulating symbol, scaling the sum signal by multiplying it by a scaling factor, limiting the scaled signal and gaining power. The scaling factor is set such that the coefficients of the Fourier series of the limited signal satisfy the specified quality criteria of the communication system.
EFFECT: increasing the efficiency of the power amplifier, reducing out-of-band radiation.
