In this paper, a reference time synchronization method is adopted with introduced changed and improved fine and refined time estimation step. The communication system on which it is tested is MIMO-OFDM based wireless local area network system. The WLAN standard adopted is of IEEE 802.11n, each data packet starts with a preamble, which consists of short as well as long training symbols. Simulation is implemented with C++ eclipse and tested for AWGN, exponential Rayleigh decaying and TGN fading channels. The plots generated by the simulation clearly show the improved performance of the introduced scheme.
