Abstract  Abstract

The invention relates to a synchronism in multi-carrier code division multiple access system and claims a method for driving capture synchronism in OFDM communication system and selecting in a small area and device thereof; the method of the invention comprises the steps as follows: driving the rough synchronism to determine the searching window; driving fine synchronism through detecting the relationship between the signal sample point subset and given value; the first signal sample point being in the searching window; driving relevant process on the frequency field for receiving signal; in the multi-output OFDM system; each of the antennas of the OFDM transmitter has an only given value; the given value is sent in continuous frequency guide mark pair; each of the frequency guide marks is sent on the same subset at the sub-carrier frequency in the OFDM frame.
