The OFDM technology is very popular in up-to-date wireless telecommunication systems: Wi-Fi, WiMAX, LTE etc. The main target of such wide OFDM applications is a struggle against multipath propagation that occurs in places with meaningful objects which have an influence on radio propagation. 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 X2 criterion. The OFDM subcarriers optimal gain method is proposed.
