1. a relevancy interval synchronization device is characterized in that, comprising:

  • One correlation means is carried out correlation operation for receive data;

    One peak value search device determines a plurality of peak values according to the resulting correlation values of this correlation operation;

    One peak intervals decision maker according to these a plurality of peak values, obtains a plurality of peak intervals, and obtains the peak intervals at sync bit place with judgement according to the length of these a plurality of peak intervals;

    AndOne sync bit is confirmed device, according to the peak intervals at this sync bit place, to obtain this sync bit;

    Wherein, above-mentioned receive data comprises a plurality of frames, each this frame includes a null symbol at least, one phase reference symbol, a plurality of general symbols, the resulting peak value of above-mentioned peak value search device comprises;

    the peak value Peak_n of this general symbol, be positioned at the front end peak value Peak_f of this null symbol front end, be positioned at the rear end peak value Peak_b of this phase reference symbol rear end, the front end peak value Peak_f of above-mentioned null symbol and the peak intervals length between the rear end peak value Peak_b of this phase reference symbol are different from the peak intervals length of general symbol, determine whereby the peak intervals that peak intervals between this front end peak value Peak_f and the rear end peak value Peak_b is this sync bit place.
