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 according to determine search window. Then passing a test signal sample a subset of known values related to a fine synchronization to the search window wherein the first signal sample point. Carry out related processing on the frequency domain of the received signal. Wherein the multi-output OFDM system each antenna of the OFDM transmitter has a unique known value. According to the known value for sending continuous pilot frequency symbol is in the form of a pair of frequency guiding symbols transmitted on the same subset of sub-carrier frequencies within the OFDM frame.
