Equalizer Training
This parameter is available when Radio Std is not 802.11b/g(DSSS/CCK/PBCC).
This specifies how the equalizer is initialized, or “trained”. The valid values are
Channel Estimation Seq Only and Channel Estimation Seq & Data. The value
Channel Estimation Seq Only, which is the default, specifies that the equalizer is
trained using only the channel estimation sequence (also called the “long sync”)
portion of the burst preamble. The 802.11a/g/n standards imply that the equalizer
