FIELD: physics.
SUBSTANCE: invention relates to the field of discrete information transmission and is used in transmitting devices of wireless transmission systems with OFDM-modulation. For this, method involves joint implementation of two limiting and filtering decisions and backup subcarriers in one reconfigurable filter, wherein in filter configuration for allocation of standby subcarriers OFDM signal is subjected to special iterative processing, value of reserved subcarriers is calculated to generate "anti-peak" signal, and in filter configuration providing allocation of data subcarriers, signal after filter and "anti-peak" signal are summed.
EFFECT: high efficiency of the system by reducing the OFDM signal peak-factor with an allowable level of inband distortion, maintaining order of algorithm computational complexity and reducing signal processing delay.
