Abstract  Abstract

A method and apparatus are provided for performing acquisition, synchronization, and cell selection in a MIMO-OFDM communication system. A coarse synchronization is performed to determine the search window. Fine synchronization is then performed by measuring a correlation between the subset of signal samples and a known value, where the first signal sample is present in the search window described above. The correlation is performed in the frequency domain of the received signal. In a multi-output OFDM system, each antenna of the OFDM transmitter has a known unique value. The eigenvalues are transmitted as pairs of consecutive pilot symbols, each pair of these pilot symbols being transmitted in the same subset of sub-carrier frequencies within the OFDM frame.
