Abstract  Abstract

This invention relates to multi-carrier code division synchronous in code division multiple access system. Providing a sort of a catch synchronization and cell selection method and a device in an OFDM communication system. Performing coarse synchronization to determine search window. Then pass through between the measuring signal sample a subset of known values related to a fine synchronization position to the search window wherein the first signal sample point. Carry out related processing on the frequency domain of the received signal. Wherein a multi-output OFDM system each antenna of the OFDM transmitter has a unique known value. A known value in a continuous pilot frequency sign corresponding to each pair of frequency guiding symbols transmitted on the same subset of sub-carrier frequencies within the OFDM frame.
