前导码

5G OFDM分为两部分,前导码Legacy preamble和数据data
在这里插入图片描述
前导码类型:
其中前导码Legacy preamble分为:Legacy Short Traing (L-STF), L_LTF, L-SIG。
如果数据是HT/VHT/HE,则还有其对应格式的前导码。

各类型作用:
L-STF:信号检测、AGC、接收天线选择
L-LTF(Long Training Field):用于频率选择和信道估计
L-SIG:计算分包的持续时间

HE-GI:支持三种类型 0.8 μs、1.6 μs 和 3.2 μs
HE-LTF: 支持三种3.2 μs(1x)、6.4 μs(2x)和 12.8 μs(4x)
