Study and realization of synchronization for wireless LAN

A simple synchronization algorithm is proposed in IEEE 802.11b WLAN system. According to the auto correlative character of the frame header, the algorithm can get coarse synchronization through power summing and peak position comparing; then get accurate synchronization by finding the SFD field from the demodulated data of the frame header. Simulation results show that the algorithm can get accurate synchronization even if the channel is very bad. It is a simple and useful algorithm and can be easily realized through hardware.
