1.一种在无线局域网WLAN系统中由第一站STA以正交频分复用OFDM模式执行的方法，所述方法包括：
基于短训练字段STF序列生成增强定向多千兆位短训练字段EDMG STF信号，
其中，所述STF序列包括A序列和B序列；以及
经由基于一个或多个空时流STS的无线信道向第二STA发送包括所生成的EDMG STF信号的EDMG物理协议数据单元PPDU，
其中，基于一个或多个STS的索引值来确定所述A序列和所述B序列，
其中，所述STF序列被定义为{A,0,0,0,B}，
其中，所述无线信道是4.32GHz信道，
其中，对于所述索引值被设置为“1”，所述A序列被定义为{0,0,+1,0,0,0,+1,0,0,0,-1,0,0,0,+1,0,0,0,+j,0,0,0,+1,0,0,0,+1,0,0,0,+1,0,0,0,-1,0,0,0,-1,0,0,0,-j,0,0,0,-1,0,0,0,+1,0,0,0,+1,0,0,0,-1,0,0,0,+1,0,0,0,+j,0,0,0,+1,0,0,0,-1,0,0,0,-1,0,0,0,+1,0,0,0,+1,0,0,0,+j,0,0,0,+1,0,0,0,+1,0,0,0,+1,0,0,0,-1,0,0,0,+1,0,0,0,+j,0,0,0,+1,0,0,0,+1,0,0,0,+1,0,0,0,-1,0,0,0,-1,0,0,0,-j,0,0,0,-1,0,0,0,-1,0,0,0,-1,0,0,0,+1,0,0,0,-1,0,0,0,-j,0,0,0,-1,0,0,0,+1,0,0,0,+1,0,0,0,-1,0,0,0,-1,0,0,0,-j,0,0,0,-1,0,0,0,+1,0,0,0,+1,0,0,0,-1,0,0,0,+1,0,0,0,+j,0,0,0,+1,0,0,0,+1,0,0,0,+1,0,0,0,-1,0,0,0,-1,0,0,0,-j,0,0,0,-1,0,0,0,+1,0,0,0,+1,0,0,0,-1,0,0,0,+1,0,0,0,+j,0,0,0,+1,0,0,0,-1,0,0,0,-1,0,0,0,+1,0,0,0,+1,0,0,0,+j,0,0,0,+1,0,0,0,-1,0,0,0,-1,0,0,0,+1,0,0,0,-1,0,0,0,-j,0,0,0,-1,0,0,0,-1,0,0,0,-1,0,0,0,+1,0,0,0,+1,0,0,0,+j,0,0,0,+1,0,0,0,+1,0,0,0,+1,0,0,0,-1,0,0,0,+1,0,0,0,+j,0,0,0,+1,0,0,0,-1,0,0,0,-1,0,0,0,+1,0,0,0,+1,0,0,0,+j,0,0,0,+1,0,0}，并且
对于所述索引值被设置为“1”，所述B序列被定义为{0,0,+1,0,0,0,+1,0,0,0,-1,0,0,0,+1,0,0,0,+j,0,0,0,+1,0,0,0,+1,0,0,0,+1,0,0,0,-1,0,0,0,-1,0,0,0,-j,0,0,0,-1,0,0,0,+1,0,0,0,+1,0,0,0,-1,0,0,0,+1,0,0,0,+j,0,0,0,+1,0,0,0,-1,0,0,0,-1,0,0,0,+1,0,0,0,+1,0,0,0,+j,0,0,0,+1,0,0,0,+1,0,0,0,+1,0,0,0,-1,0,0,0,+1,0,0,0,+j,0,0,0,+1,0,0,0,+1,0,0,0,+1,0,0,0,-1,0,0,0,-1,0,0,0,-j,0,0,0,-1,0,0,0,-1,0,0,0,-1,0,0,0,+1,0,0,0,-1,0,0,0,-j,0,0,0,-1,0,0,0,+1,0,0,0,+1,0,0,0,-1,0,0,0,-1,0,0,0,-j,0,0,0,-1,0,0,0,-1,0,0,0,-1,0,0,0,+1,0,0,0,-1,0,0,0,-j,0,0,0,-1,0,0,0,-1,0,0,0,-1,0,0,0,+1,0,0,0,+1,0,0,0,+j,0,0,0,+1,0,0,0,-1,0,0,0,-1,0,0,0,+1,0,0,0,-1,0,0,0,-j,0,0,0,-1,0,0,0,+1,0,0,0,+1,0,0,0,-1,0,0,0,-1,0,0,0,-j,0,0,0,-1,0,0,0,+1,0,0,0,+1,0,0,0,-1,0,0,0,+1,0,0,0,+j,0,0,0,+1,0,0,0,+1,0,0,0,+1,0,0,0,-1,0,0,0,-1,0,0,0,-j,0,0,0,-1,0,0,0,-1,0,0,0,-1,0,0,0,+1,0,0,0,-1,0,0,0,-j,0,0,0,-1,0,0,0,+1,0,0,0,+1,0,0,0,-1,0,0,0,-1,0,0,0,-j,0,0,0,-1,0,0}，以及
