<P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for performing acquisition, synchronization, and cell selection within an MIMO-OFDM communication system. <P>SOLUTION: A coarse synchronization is performed for deciding a search window. Then fine synchronization is performed for measuring correlation between subsets of signal samples. A first signal sample among the signal samples exists within the search window, and has a well-known value. The correlation is performed in a frequency area of a reception signal. In a multi output OFDM system, each antenna of an OFDM transmitter has a unique well-known value. The well-known value is transmitted as a pair of continuous pilot symbol, wherein each pair of pilot symbols is transmitted by the same subset as sub-carrier wave frequency within an OFDM frame. <P>COPYRIGHT: (C)2009,JPO&INPIT |
