Synchronization is a very important issue in communication systems. In this paper, it presents the implementation of the frame synchronization in burst Orthogonal Frequency Division Multiplex （OFDM） communication based on Std IEEE 802.11a. The algorithm of frame synchronization is on the base of the classic Schmidl-Cox algorithm and detects a certain sample length. It can avoid the impact of the larger random noise, compared to the traditional packet detection algorithm. The frame synchronization is realized by the use of ten repeated short training symbols to determine the starting position of the data packet. Furthermore, the entire frame synchronization is implemented by Xilinx Field-Programmable Gate Array(FPGA) Virtex2 device.
