Abstract

In this paper, efficient time synchronization scheme for OFDM based WLAN system and its performance simulation results are presented. Assuming AGC and packet detection is done within 7 short training symbols. This scheme consists of coarse and fine estimation, and exhibits robustness over fading and AWGN channel. The presented synchronization scheme achieves the success rate of about 96% over the SNR of 5 dB.
