| Abstract: | Wireless local area network communication equipment is usually based on an ad hoc network operation. A frame synchronization detection method is proposed for multi-band orthogonal frequency division multiplexing （MB-OFDM） system to identify piconet and symbols timing. The detection method is based on having correlation of the received and expected local storage of 12 or 24 packages/frame synchronization symbols. The most possible timefrequency code is chosen from the statistics of these correlation results for receiver decoding. The test results show that system stability is greatly improved. |
