description FIELD: engineering of communication systems. ^ SUBSTANCE: communication system has transmitter, meant for transformation of serial data stream to parallel data and for segmentation of parallel data on multiple blocks, having multiple data blocks; for inserting supporting data, having information, representing value of phase or position, where supporting symbol is inserted, into each segmented sub-block; reversed fast Fourier transformation of responsible block into time signals, wherein frequencies of sub-bearing lines are separately assigned to data blocks; and determining phase multipliers of reversed fast Fourier transformation subjected time signals for decreasing ratio of peak power value to average power value, where nonlinear distortion occurs due to match of phases between reversed fast Fourier transformation subjected data blocks and sub-bearing frequencies; and rotation of phase of reversed fast Fourier transformation subjected signals in accordance to determined phase multipliers prior to actual transmission. ^ EFFECT: decreased ratio of peak power value to average power value. ^ 6 cl, 12 dwg
