| Abstract(in English) | In this paper, we propose a novel scheme of Preamble which is utilized for time/freqeuncy synchronization and channel estimation for MIMO-OFDM. Synchronization for MIMO-OFDM is processed by received signals over fading from transmit antennas respectively. Preamble must be separable, because it is necessary to utilize a transmit signal from received signal which is mixed by several transmit signals on estimating a channel. Therefore, we have to design a preamble with good correlation performance and separability. By using computer simulation, we report that the proposed system has good performances for symbol timing, frequency offset estimation same as conventional system. Specially, the proposed system had a better performance on channel estimation with residual frequency offset after frequency synchronization than conventional system and fast acquisition using simple algorithm. |
