Abstract  Abstract

The invention claims a synchronous multi-carrier code division multiple access system. A method and device for capturing synchronous and cell selection is performed in the OFDM communication system is provided. performing coarse synchronization to determine the search window. then through measured related to signal sampling point subset and known values between fine synchronization is performed wherein the first signal sample point is in the search window. execute the relative process on the frequency domain of the received signal. In a multiple-output OFDM system each antenna of the OFDM transmitter has a unique known value. sending the known values as pairs of consecutive pilot symbols form each pair of pilot symbols transmitted on the same subset of subcarrier frequencies in the OFDM frame of.
