FIELD: communications.
SUBSTANCE: method includes stages in which OFDM characters are transmitted in such a way that data character size of particular OFDM character in each frame is set smaller than data character size of typical OFDM character within mentioned frame, OFDM characters are received and correlation factors are correspondingly calculated for this particular OFDM character on the basis of both corresponding data characters time-slot and data characters time-slot of typical OFDM character, phases of corresponding correlation factor are selected respectively which factor is calculated according to mentioned particular OFDM character, decimal part of frequency shift is evaluated and integer part of frequency shift is determined which part matches to decimal part of frequency shift thereby evaluating full frequency shift and achieving frequency synchronisation.
EFFECT: providing possibility to obtain precise initial frequency shift.
