| 摘 要： | 阐述一种用于IEEE 802.11g的帧头类型识别的方法与具体硬件实现方案。该方法利用IEEE 802.11g协议中两种帧头的不同特点,使用相应的匹配滤波器,根据相关结果识别出帧头类型。方法的新颖点在于,只取接收信号的符号位进行相关运算,并在检测判定之前有意地加入了载波调制,提高了检测方法的性能。

| Abstract: | In this paper,we provide an novel method and hardware implemention scheme to detect the type of IEEE 802.11g's frame preamble.The method incord to the different characteristic of the two type frame preamble,using specifically match filter,detect the type of preamble by atocorrelation sum.Our inovation is accomplished by reducing the correlations to just the sign bits of the received samples,and adding carrier modulate before detecting,this can improve the method's capability. |
