CORRELATION METHOD AND APPARATUS FOR ACQUIRING SYNCHRONIZATION IN WIRELESS LOCAL AREA NETWORK |
摘要 |
Provides is a correlation method for acquiring a synchronization in a wireless local area network (WLAN). In the correlation method, an auto-correlation value is measured in a receive (RX) signal based on the WLAN standard by use of a successive partial short preambles. A time point when the auto-correlation value becomes smaller than a predetermined threshold value is detected. A cross-correlation value for the successive partial short preambles is measured from the time point when the auto-correlation value becomes smaller than the predetermined threshold value. A time point when the cross-correlation value becomes maximum is determined as a reference time point for synchronization acquisition.
