IEEE802.11n Time Synchronization for MIMO OFDM WLAN
A. Ali, W. Mahmood, I. Javed, and I. Ur Rehman
Abstract—In this paper, a reference time synchronization method [1] 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.
Index Terms—IEEE 802.11n, MIMO, OFDM, time synchronization, WIFI, WLAN.
