N2 - Several new symbol timing synchronization algorithms for orthogonal frequency division multiplexing (OFDM) system based on IEEE802.11a are put forward. First, frame synchronization technology is studied in technology of symbol timing synchronization. According to the frame synchronization algorithm based on energy detection, an optimized algorithm named sliding window-counter algorithm based on two-sliding window algorithm is put forward, the optimized algorithm can provide more space between performance and resource consumption of ASIC realization; According to the frame synchronization algorithm based on cross correlation, a new algorithm of frame synchronization using a period of short training symbol in IEEE802.11a is put forward. Then, according to inaccuracy of symbol synchronization in multi-path fading channel, new solution is put forward by studying a period of long training symbol sequence in preamble. Simulation results show that these algorithms could finish accurate timing of symbol synchronization in worse channel.
