Hi all,
I am using the new OFDM PHY to get data from USRP. The new OFDM PHY is
using pilot subcarrier. I think that it using the pilot because it want
using pilot to help decode the data subcarrier. But when I checking the
source code in the channel equalizer, I didn't find any code that using
pilot to help decoding.
According my opinion, the equalizer just updating the channel state and
didn't do anything except that. We should do interpolation using the pilot
subcarrier channel state to help decoding the data, right? But the source
code didn't do that.
So I am wondering why the new ofdm PHY code using the pilot.
Thanks
