Sync signal detection method and radio communication system

摘要

A sync signal detection method for receiving a sync signal regularly radio-transmitted from a predetermined station at a predetermined cycle and detecting the received sync signal is used in which a cycle at which a sync signal is detected is judged, a detection window having a predetermined width is set every judged cycle, and only a sync signal detected from received signals in the detection window is judged as an effective sync signal. The method makes it possible to set sync timing by detecting a sync signal to be transmitted when performing radio communication through a radio LAN or the like.
