Performance analysis of OFDM burst synchronisation algorithms

In this paper, four frame synchronisation algorithms for OFDM systems are examined for preamble-based time synchronisation. However, the performance of the frame synchronisation depends on the threshold pre-defined. The performance of these algorithms is analysed in terms of estimation mean and variance of optimum frame position. The threshold can be also determined based on the mean of the optimum frame position. The simulation results related to the IEEE 802.11a WLAN model are provided to verify the analysis.
