比如below, HT, 40 MHz, non STBC,该怎么正确解析LLTF和HT-LLTF在raw Data中的对应的子载波索引?我按照官方文档所示,先将raw Data((虚部在前,实部在后))虚部和实部两两对应组合为复数,然后解析前64个元素,即下标0到63为LLTF的子载波索引,LLTF在此情况下无负子载波索引,然后解析下标64到127,一共64个元素对应于HT-LTF的子载波索引0到63,再解析下标128到193,一共64个元素,对应于HT-LTF的子载波索引-64到-1,随后将前后两部分对调拼接成子载波索引-64到63的csi序列,但是我解析HT-LT的相位时,为何在子载波索引0左右位置会出相位的跳跃呢?
