The simulation model for OFDM (Orthogonal Frequency Division Multiplexing) signal energy characteristics research is developed. The OFDM signal vector-phase states are examined. The momentary amplitudes distribution function is obtained. A hypothesis of amplitude distribution law is verified by the chi-square criterion. The OFDM subcarriers optimal gain method is proposed.
