提出了一种适用于IEEE 802.11a WLAN(Wireless LAN,无线局域网)系统的帧检测时域同步技术,在使用门限机制的延时相关帧检测的基础上,利用短训练符号的互相关信息共同来完成802.11a帧的同步检测。
A frame detection time-domain synchronization technique suitable for IEEE 802.11a WLAN (Wireless LAN) system is proposed. Based on the detection of delay-dependent frames using the threshold mechanism, the cross-correlation of short training symbols Complete 802.11a frame synchronization detection.
