A NOVEL TIMING SYNCHRONIZATION METHOD FOR DISTRIBUTED MIMO-OFDM SYSTEM

Orthogonal frequency division multiplexing (OFDM) is a popular method for high data rate wireless transmission. Its capability of turning a frequency-selective channel into a parallel collection of frequency flat subchannels has attracted huge interest from the research community as well as the industry. Multiple Input and Multiple Output (MIMO) configuration is also a hot topic for the merit of an increased diversity gain and/or a higher system capacity. In this contribution, a novel timing synchronization method is proposed for the distributed MIMO-OFDM configuration. The performance of this proposed scheme is evaluated by simulations. The simulation results show that the proposed method offers an accurate estimation on the different time delay caused by the distributed transmitters of the MIMO-OFDM system.
