| Zusammenfassung: | A detection and synchronization device of IEEE 802.11a or HiperLan2 frame head is featured as utilizing match filter to carry out inter-correlation operation on short Preamble series for obtaining a correlation series, determining that standard signal consistent to IEEE 802.11a or HiperLan2 is detected out and seeing that synchronous position can be confirmed preliminarily according to it if specific correlation peak value situation is obtained i.e. wave peak appeared in equal distance continuously and then no wave peak exceeding threshold in the same distance. |
